Allen, meanwhile, threw for 254 yards and was picked off twice, with one interception returned by linebacker C.J. Mosley 17 yards for the Jets’ first touchdown of the season. But Mosley, who also recovered a fumble, injured his groin muscle as the game went on and was not on the field during the Bills’ comeback.

“We’ve got to take this lesson in stride,” Mosley said afterward. He joined the Jets in the off-season after five years with the Baltimore Ravens, and this was hardly the way he wanted the new chapter in his career to begin.

The same could also be said for the Jets’ new coach, Adam Gase, whose team had command of the game until it suddenly didn’t.

“We were just inept on offense, making mistakes that we can’t make to consistently move the ball,” Gase said. Darnold, meanwhile, pointed out that the Jets forced four turnovers and did not commit any of their own, but still lost, anyway.

It may not have helped that Bell, who signed as a free agent after a one-year holdout, touched the ball just six times after the Jets took the 16-0 lead. Jets receiver Jamison Crowder did catch 14 passes, which is a lot, but the receptions netted only 99 yards, which isn’t all that much.

“We didn’t take advantage of the way the defense played,” Crowder said in a nod to some, but not all, of his teammates.
