Wing-T

QB under center. Fullback directly behind him at ~4 yds (the 'buck' — his dive fake starts every series). Halfback offset to the WEAK side at ~4.5 yds. Wingback on the STRONG side, just outside the tight end and OFF the line of scrimmage. Split end weak, on the line, at a tighter-than-normal split. The wing is what separates this from Pro I or Pro Set: it puts a third run threat on the edge with no motion, so the defense has to defend both flanks with the same 7 box defenders. Tubby Raymond's Delaware Wing-T is the canonical version. Why coaches still run it: it wins with technique and timing rather than size, every play starts identically for the first second and a half, and the counters punish a defense that flows fast. Why it's hard: it demands disciplined pulling guards and a lot of backfield-footwork reps, and the passing game lives almost entirely off run action rather than dropback. Best fit for a team with quick, undersized linemen and two or three willing ball-carriers rather than one star back. Distinguished from the Double Wing (two wings, no split end, tight line) and from the Wishbone (three backs in a Y, no wing).
