Does your QB really deliver?
The stat that only counts the drives that actually mattered — tied or down a score, 4th quarter or overtime, no kneel-downs, no garbage time.

Chances on the bottom axis, Clutch Factor going up. Bigger dot = more drives actually delivered. Top right is where legends live.
Clutch Factor = game-winning drives ÷ opportunities. An opportunity is any drive where a QB's team gets the ball tied or down by one score, with the drive itself starting in the 4th quarter or overtime — not just running into it from the 3rd.
A drive counts as a win when it ends with the team taking the lead for good and they go on to win the game outright — no credit for a tie, and none if the opponent answers back. What happens after doesn't matter: if the defense pads the lead to three scores afterward, that's not on the QB.
Every quarterback here has thrown at least 25 passes in the 2025 season, or has 10+ career starts and is still considered a starter or high-end backup — plus a short list of retired greats (Brady, Manning, Favre, and others) with enough career volume to belong in the conversation.
Kneel-downs, drives that started before the 4th quarter, and any drive where a second QB entered and threw more than a single stray pass.
Trick-play touchdowns thrown by a non-QB, and pure-rushing drives — both credited to the QB actually running the offense that game.
