If you look at the production Manning had before he tore his Quad, his numbers went down significantly after the injury.
What concerns me with our secondary is that they look great against sub-par/mediocre teams, but get lit up against the elite teams. Honestly, I hope the Jets game was just an anomaly, but when you look at Fitzpatrick's career and how inconsistent he's been, it was very disheartening to see our secondary get burnt all game long.
In regards to the contract, the Bills are already close to the cap. There are a lot of other players and positions that the Bills will need cap room for. For next year, the only WR under contract is Watkins, so the Bills will have to pick up some WR's in FA and/or draft players at that position. Watkins contract will be coming up in a couple of years and with Whaley moving up to draft him, you know he's going to want to keep him. I'm not sure how long Zach Brown and Lorax are under contract for, but the Bills have some decisions they need to make with those two. Do the Bills give those two a pay increase/longer contract or do they let them walk?
