The offense is diagrammed in what was for some time referred to as a "pro set"-- "set" indicating that the players are stationary, although one back may go in motion from it. This particular version is said to have a "deuce", "flank" backfield. From the description above of the straight T, this formation can be seen to be derived by splitting one end and moving the halfback on the opposite side to a flanker position. Instead of "SE" and "FL" for those positions, however, we see "WR", for "wide receiver".
