Sean Mannion

Mannion has the fewest starts of anyone on this list – he’s 0-2 as well – and that’s the biggest knock against him as a backup. The Jets can’t afford another situation like 2019 where the backup quarterback doesn’t have enough starting NFL experience to run an offense. Mannion has 74 career passing attempts since he was taken in the third round of the 2015 draft by the Rams and has never thrown a touchdown.

The Jets need someone who can quickly pick up Gase’s offense and play at a high level if anything were to happen to Darnold. Signing Mannion would be worse than re-signing any of the Jets’ backups from this past season.
