That’s exactly my point. None of these have to deal with a defensive playbook. I can show you the 5 pages of fronts Kyle Shanahan’s QB and linemen have to identify defensive fronts. A defensive end only has to know if he has a 2 or 3 man surface and any front/stunt adjustment.
I’ll list the 3 things that defensive ends need to know regarding a defensive playbook in a 4-3:
Maybe 1 fire zone blitz
Now their technique needs to be on point. They have to read the tackles block, block down step down, react to potential screen, look for any reverse or orbit motion, block destruction against a pulling guard or fullback. They have to have good hand fighting skills to get off the blocks.
I am just curious, which team do you think did the whole suck on purpose for a franchise QB well? Im a little foggy headed on this one, but I can't think of a team that has tanked on purpose and became perennial winners.
