re: The "not ready" or "he will be ruined" are the dumbest excuses, I'll prove it

This game is so much more than reps compared to the way it used to be played. It is also way more complex than most people know - linemen don't just block, backs don't just take the ball and run.

The LT has become the most important lineman when 20 years ago it was the RT who was the most critical. The center's role has become vital. It's hard enough to concentrate on making a good snap while also making a good block (particularly against a LB) but the modern center must also go to the line and bark out assignments to the linemen around him. The QB - set aside the skill level required. The ability to read a defense pre-snap, decisions to be made on option plays, vision of the field while "feeling the pressure".....all require split second decisions based on what the defense is showing you/doing and the play that is called. The best QB is a coach on the field. You can't say that about any other offensive position.
