It sounds like this a anything goes type of thread. So here are my suggestions for trick plays.
Put Sam Paleauscu(sp?) on defense and have him blitz.
Since Brad Johnson is the field goal holder, if it 4th and less and 2 and we set up to go for a field goal, fake it and have him throw it to Bennett for a first down.
Flea Flicker to Miles Austin. Have Williams and Owens lined up on the outside and Austin in the Slot. Williams can go 20 yards and then curl. Owens can do an in and out pattern. And Miles Austin will do a stutter and go and with all the attention drawn on Owens and Williams, he will be open.
