Philly has the tush push. Other teams have the regular QB sneak or the smash mouth formation. Everybody, on the defensive side, is crowded up the middle ready to scrum. What if Texas pulled Manning,  brought in KJ Lacey, split Coleman wide, and shocked everybody on the defensive side by lining up a massive TE to play fullback with Smothers and Brown lined up in the Wishbone. I would like to see the reaction from the defense.

Could it work?  

Need six o-linemen up front with a Casey Studdard attitude.

Disagree.  In this situation you have 5 OL and a blocking TE with the DL and LB's crowded inside to defend the inside run. Coleman  will pull a corner and a Safety out of the play. With Lacey running the play, the pass is still in play. At the very least, you will force the defensive team to burn a timeout or get caught in a race to the sidelines.

flood would pull the guard and center and they would get blown up in the backfield
