Another couple of coaching points.
Put a starting LB at the force position. They are tougher and give better looks for the guard.
Have a shield holder outside the force player to represent the corner. Have the BST haul ass on the touchdown block. This is tough so I will sub a back up tackle after 3 times in a row.
Same goes for SE or BSTE have a shield holder at the FS position and have them haul ass for the cutoff block.
If you guys are like our teams you will have an army of useless "WRs" Line up two and have one run the cutoff block and one run a called route. Have the QB hand the ball off and a coach with a second ball hand off to the QB off his fake where he runs waggle and throws the called route by coach.
I haven't done it in awhile but during the drill when the team was getting winded I would yell "Run the Sweep!" and the offense would respond to "To Win!" It helped set the mind set.
