re: How about we bench MILES for 1 game and WE make the lineup...

Offense
QB - Harris
RB - Buga (rotate rest. stay with hot hand)
WR - Dural
WR - Dupre
WR - Slot (rotate)
LT - Collins
LG - Vadal/Boutte/etc
C - Dodd
RG - Pocic
RT - Hawkins
TE - rotation

This is base set. This has become the standard pro-style offensive set in NFL. You can still run power with this grouping. Spreading field will get people out of the box. You can run multiple formations (QB under center, pistol, shotgun) and still run the ball (straight handoff, delays, draws, misdirection, etc.). Opens up play action more. Gets TEs and RBs more involved in passing game.

LSU did this the 2nd half against Wisconsin successfully. We have not seen it since. Why?

The old 70s, "21 personnel", Air Coreyell offense is no longer effective and needs to be limitted or shelved.
