CoachRob, I found the defense very simple to install. Even with that I still have to remind the boys regarding alignment..OLB's floating too far back...MLB starts cheating up, my strong side CB last game actually pulled himself way up inside of our DE!! I asked him what he was doing and he said he was getting bored and wanted in on the action...had to hammer him a little. I haven't introduced the stacks yet however. If your facing a sweep team, what I tried and found worked very well was repping the shoot the sideline pursuit drill exactly as Jack describes. I walked the pursuit angles with every player first, both sides, sped up the drill, then went with the two backs facing each other full speed, wrap drill. I make all the boys do their job and then 11 helmets to the ball full speed. Don't forget and make sure the back side CB slow plays then caps the alley and DE's are disciplined in their pursuit angles..they start to get lazy after a few reps..don't let them do it. I don't think we've given up 5 yards on a sweep play yet..the compress and get them running east/west, protect the alley concept is great. We were burned once however on a cutback..important to make sure OLB's know the correct pursuit angle...once the RB see's he has no where to go on the sweep, he might try and cut back through the C gap. I run the Red call only, line 'em up and let 'em play.
