I don't know about three years. We went from 1-15 to 12-4 in two years, if Douglas is a decent GM he can have us competitive by next year. For a young QB a RB like Bell is an important guy to have around. Can't just strip it down and expect Sam to develop in a vacuum.
The entire offensive line need to be rebuilt. This team needs 2 wide receivers, assuming Anderson leaves. I have no faith Enunwa's ever going to stay healthy.
The defense is always one year away from being a legitimate playoff unit, and even with the lack of quality CBs and a pass rusher, I still think it it's close.
But things are going to change. How much longer can McClendon play? Anderson has disappeared. Q could be a star, but we have to assume Leo is gone. As much as we won't like it, the defense will need to be addressed in the draft.
And we need 5 offensive linemen. I know guards grow on trees, and all, but you're not replacing at least 4 of them (hoping Edoga pans out) in one year.
4 OL
2 WR
2 CB
1 OLB
1 DL
At minimum, that's 10 players that need to be acquired. The Jets, for once, aren't going into an offseason with deep pockets. It's going to take a couple of years to get the personnel built.
