Jets waived RB Joe McKnight. McKnight entered the summer firmly on the roster bubble, but seemed to be saved by Chris Ivory's injury woes and Mike Goodson's legal troubles. That was not the case, as McKnight barely practiced in camp thanks to injury issues of his own, including a concussion and migraines. McKnight is a solid kick returner, but rushed the ball just 112 times in three years in New York, averaging 4.5 yards per carry. He's had durability issues. His special-teams prowess should land him a new job in relatively short order.
