If your back doesn't have the wheels, keep him in the backfield to protect the QB as he passes. One back in the backfield, slot receivers on each end of the line, a TE to the right and a wide out to the left define this package. Also called an Ace formation. Two tight ends buttress the O-line, and a wideout lines up on each sideline. Run outside with a speedy back or pass to your tight ends out of this set.
Trips is designed to cause confusion and get DBs tied up in coverage.
Three receivers line up to the left of the line, with one tight end on the right. Since this play commits so many defenders to the left, it can be exploited with an outside run to that side as well. Two slot receivers and two wide outs line up on either side of the formation. Great for downfield passing routes or suprise runs. The Pro Form is the most versatile set in the game.
