re: Concerning our receivers getting separation...

LOL, as an old lineman myself I've always saw it as the same thing as an OT facing a quick DE, just over a much narrower front.

The first move by both probably decides the final result.

Much technique involved, which shoulder are they over, head-over, first step, etc.

Basically, much like a DE, if that WR gets the position on the DB, he's off and running (barring holding). If that first step gets you on the hip, or the DB turned at the wrong angle- you won.

For the DB, if you can stay square and impede- you won. If he's hand fighting and the feet aren't going anywhere- you won.

Remember, contact is allowed as long as A) in front of receiver and B) not in air.

So your separation in college has to be pretty good, and especially where they can't get to your front otherwise they just keep jamming you. That's why staying square is so important.

All this screams technique with strength only enhancing the effectiveness of the technique.
