you dont have to give him a clock tell him to make a decision by the mesh point, which in gibbs world is 3 steps then get north/south...
guess what is also given 3 steps? the ol decision to take or get to the 2nd level......
if you coach the back that he can be wrong it times up beautifully.
I know, I know. Maybe it's just me, but I hate defenders EVER being able to release. And as I said, we don't run zone, although we use a lot of the concepts.
I think the biggest thing that limits explosion runs (or whatever you want to call them), is defenders that have been driven back eventually releasing laterally. The O-Lineman hits the defender, the defender gets driven back a bit, the RB heads around the edge, and the defender sees it and takes off for the sideline and is there when the RB cuts inside the CB (or whoever is running around out there).
So many videos of youth teams on outside plays show decent initial blocking on the inside, and then seven defenders end up on the ball near the sideline, while the O-Line is still standing in the middle of the field.
I'm not saying it's right, I'm not saying it's wrong. I'm just saying that's how I look at it.
