Trench Dictionary · D-Line

Wide-9

An edge rusher aligned far outside the tight end, angled at the quarterback — pure speed-rush alignment.

Also called: wide 9, wide nine, 9-technique, 9 tech

The wide-9 puts the edge rusher way outside the tackle — outside where a tight end would line up — often in a sprinter's stance aimed at the quarterback's launch point. It trades run-gap discipline for one thing: the fastest possible path to the passer, forcing the tackle into a footrace on every dropback. Offensive tackles hate it because the rusher's angle stretches their kick-slide to its breaking point. It's a passing-down weapon; against the run, someone else has to make up for the vacated edge.
