Has anyone looked into this?
A few things.
1. Does solid WR Run Blocking (and STR, but most CB don't have high STR) improve Run Plays, especially Outside Runs?
2. Does solid Run Blocking and STR 'wear down' a CB so he fatigues faster, thus being pulled more often or risking injury more often?
The idea is to put the hurt on CBs so that Back Ups come in who are general Slower and Weak Tacklers so there is more open space on the Outside and less 'chasing' or 'tracking' to the ball (as in theory 2 Defenders are completely taken out via Blocks they just can't handle).
This would also include Nickel and Free/Strong Safety, but Safeties generally have STR so you'd need really exceptional Blocking WR to get to those guys and lock them down (TE helps here).
Would also be interesting to see things like 4 Wide Receiver Set facing Dime, with 4 Run Blocking WR on a Run Play.
Just tossing some things out and looking to see if anyone has experience with this stuff.
