3 Offensive Line Tips for Full Slide Protection

More and more teams are using a lot more gap or full slide protections from football teams. I found a pretty good video over at on Gap and Full Slide Protection by Pat Perles, formerly of North Dakota State. This blog post will give you a free clip of that video, brought to you by eFootballFlix, and it will give you 3 tips I grabbed that I thought would be helpful. But first, let’s discuss what full slide protection is.

Basics of Full Slide Protection

Full slide protection has the offensive line go all in one direction. The tight end, when on the line of scrimmage, may be involved in the same slide direction.

Full Slide Protection to the Right

Back Goes Left, Line Full Slides Right

A movement player, like an H back or a runningback, slides to the opposite direction of the line.

So if the runningback goes left, the offensive line goes right.

NIU’s Empty Formation QB Power / Counter Combination Play

Northern Illinois has a pretty nifty offense. It seems to be all the rage these days. However, when you watch the film, the vast majority of the offense relies heavily on the old, reliable power blocking scheme. In this case, since they run QB power from an empty formation, they’re kicking out the end with the guard in this specific usage of the power scheme.

You may consider this a trap play, but it’s using the power blocking concept (specifically the “counter” play scheme, with the QB’s read acting as the “wrapper” typically filled by the fullback or pulling tackle).

They run a lot of QB power, and this article will focus on their combination QB power play with the jailbreak screen. Continue reading

Hidden Secret of Offensive Line Blocking

There is one absolutely hidden and poorly coached aspect of offensive line blocking. So many coaches fail to coach it up, but they look for buzz words to try to get the kids to fix the problem. I’ve only run into one or two coaches who actually practice this critical aspect of offensive line blocking, and each one experiences tremendous success and never really has a problem with this issue.

Want to know the best part of that? One coaches youth football and one coaches college, so you know it’s applicable every where.

Now, this is run blocking specific. I detail it in my e-book, Developing a Physical and Aggressive Offensive Line, but it’s not found in many other places. So I’m going to give you a sneak peak right now, for free. Continue reading

Inside Zone Blocking: Simplify Your Running Game

Are you already feeling behind coaches? The season is a few weeks away for most high schools and colleges, and many teams running game is already behind. Well, if you’re ever in doubt when it comes to a good running scheme that will simplify both technique and mental workload, consider Inside Zone blocking.

Notice how I didn’t say Inside Zone. I said Inside Zone blocking. Why so specific? Because Inside Zone blocking can be used in any scheme, it is essentially dummy proof, and the rules are simple. While over-simplification can get you in trouble, inside zone blocking is a relatively safe concept if you’re kids are struggling with other inside running schemes. Continue reading

Eliminating False Start Penalties

Yep, every offensive football coach deals with false start penalties. Every coach tries to deal with it after they notice the problem. Coaches, here’s your issue, it’s too late if it’s already a problem. Sure, you may help the issue. But if your offensive line coach AND the quarterbacks coach didn’t start planning it from day 1, you’re going to have issues.

Why do I say the quarterback’s coach as well? Because the Quarterbacks have to change their cadence on every snap in team as well so the whole offense gets used to it.

Changing The Cadence in Practice – Offensive Line

I feel like this year, our freshmen squad is tremendous at going on multiple counts. Why? We addressed it right away. If they jump, it’s up downs for everyone. I gave them a free-bee or two on the first couple of days, but after that I’ve been very strict on it.

Every time we did any drill, I would give them a count. When I don’t give them one, they ask. That’s when you know they respect the importance of going on a different snap count, even in practice.

Changing The Cadence in Practice – Quarterbacks

Quarterback coaches should make sure their QB’s change the snap count. When a play is given in the huddle early on, tell the QB what snap count to go on. If you can’t remember to do this, build it into your script. Next to the play, write “on 2″. Quarterbacks should change the play count they’re directly calling a play. Working on timing with the backs? Have the QB dictate the snap count. Working inside with just the line or in 7 on 7? Have a different snap count.

Understand that certain plays probably should go on certain snap counts, especially with younger players. Running jet sweep? Go on one or on set. Running a play with jet motion across the formation, go on two. Defenses will start to tee off on jet sweep or other plays like this if you don’t do these things. So drill it in practice with those specific plays.

If quarterbacks aren’t drilled on changing the snap count, they’ll constantly use the same snap counts in team drills or in games. Then your team will get used to it. Teach the importance of why you change the snap count. Let’s remember how it can be important.

  • Keep the defense from jumping the count
  • Disguise a play call (like jet sweep)
  • It can get us free yards or a free play
  • Identify a blitz/coverage

Teaching the players to understand the importance of changing the snap count will hold them more accountable across the board. When importance is placed on an element, it also earns focus from the players. A lot of coaches say a snap count is imporant, but don’t really explain the full depth of it’s importance. Don’t make this mistake.

Conclusion on Snap Counts

Make sure you start every season by emphasizing their importance by personally changing them up in your drills. Don’t accept failure in this regard, and make sure you emphasize the importance overall.Also, make sure you check out

Why Offensive Line Coaches Need to Understand Defensive Run Fits

I’ve touched on the topic of offensive line coaches understanding defensive run fits in the past. But it is absolutely critical that offensive line coaches spend time with their defensive coordinator in order to understand how defenses defend plays. Then, the coach needs to take this information to the next step and equip their plays to be better prepared for well coached teams. I’ll use a simple example, weakside iso versus a 4-3 over cover 4 front, to show the importance of understanding defensive run fits.

Offensive Line Coaches Understanding Run Fits: “The Play Looks Wide Open Coach!”

Or… “It’ll be there all day!” Then it’s not. We’ve been there as O-line coaches. The defense makes an adjustment. For instance, below is an example of weakside iso versus the 4-3 over front. Every offensive line coach licks his chops when he sees this. There’s a big, natural bubble, and all we have to do is get a body on a body.

Weakside I Formation Iso versus 4-3 Over Cover 4

Weakside Iso versus 4-3 Over

I always assume the defensive coordinator is smarter than me. They’re not giving me a huge bubble unless they’ve got a way to protect it. In other words…

It's a Trap!

As many o-line coaches find out the day after film, while we draw it up and it looks perfect, the execution kills us. That’s because good defensive teams understand run fits and they do them so often that this play get’s clogged up. As you can see below, it was indeed a trap. The Mike linebacker has strongside B, the safety fills outside, and the Will linebacker plugs the kickout by the fullback. In other words, it’s hard as heck to get movement on the double and get to the Mike linebacker with a traditional horizontal combination block through the nose tackle.

4-3 run fits versus I formation Weakside Iso

Notice the bad angle for the combo to keep the Mike from Inserting Inside the Fullback

The Mike scrapes to B gap, and inserts inside of the Will linebacker, who should be taking the block on with his inside shoulder. Even if the Will linebacker takes it on wrong, the Rover is there. We can’t account for the Rover unless we get into some double tight sets OR use a receiver and get to him. So let’s assume the Will does forces it back inside.

On top of this, the Sam is probably flying to strongside A gap because the backside safety can take C gap. So now, we’re in a tough spot. ┬áThree linebackers who are scraping fast towards the play. We’ve got to combo a nose AND hope the backside tackle takes a great path to the strongside linebacker.

Offensive Line Coaches Understanding Run Fits: Offensive Line Technique

As an offensive line coach, need to understand how your conference opponents will insert their run fits against your run game before the season starts. Why? Because then you can really focus on teaching the skills necessary to play their run fits, not where they are going to be at the snap.

For instance, in the diagram below, we see a vertical combo block on the nose tackle through to the Mike. You may not get the dominating combo, but you will get a body on a body. The crease here in the 4-3 over weakside B gap is big enough naturally that the tailback should have no problem punching it through if the guard and center can get some vertical displacement on the nose and just come off to the Mike.

Weakside Iso versus the 4-3 Over Cover 4 with better technique

Notice the vertical combo on the nose tackle to the Mike.

The tailback also needs coaching here. He needs to trust that his linemen will come off off onto the Mike. If he cuts back at the line of scrimmage, he will run into cutback defenders. He should stay inside, true to the hole. It probably won’t be terribly clean, but he should be able to punch it through for 5 yards if not much more.

We also see the tackle and guard on the backside stepping tight together. This is almost a zone combination. Some coaches would say combo the backside defensive tackle to the Sam linebacker. I feel that the tackle, even on the vertical combo, can step too hard and knock the defensive tackle into the A gap in this scenario, closing that window for the linebacker, which in turn makes him press tighter to the playside because well coached linebackers go to the next open window. I’d rather have the backside of the offensive line here use a mentality like, “you two have those two”, and really zone through. So that way, if the 3 technique works into the offensive tackle, the guard can slip off for the Sam. If the defensive tackle gets hands on the guard, like he probably will, the offensive tackle will step inside (no matter what he’s doing that) and work on a 45 degree angle inside up to the Sam.


By taking time to understand how the Mike will flow (aka, his run fits), I will know to coach our guys to use a vertical combination block in this scenario, rather than a horizontal combo. Some offensive coordinators may need to be “schooled” on why that nose tackle shouldn’t be completely blown away by the combo. You need to care more about getting to the backer on this play. For winning teams, while it’s nice to physically dominate the defensive line, it’s better simply to get a body on a body so that way the running back can use his vision. So overall, when scheming plays, you need to make planning for a defense’s run fits a priority. is a place you should visit today. They have some great drills that can help you.
