My thoughts?
IF it could happen:
Extend (maybe) Devin McCourty to free up some $$. I can't believe he'll retire given the level he's playing at, but in the end, that's his call.
Sign Mo Harris when he's available IF either Dorsett or Gordon look to be longer term.
Trade Michael Bennett for OJ Howard or Cameron Brate or some other TE (or sign Dwayne Allen if he's healthy and trade for a better OL). I love Bennett and would love to see more of him, but I'm beginning to suspect that Chase is simply stealing his role. Bennett's on a reasonable deal and can still excel in the right schemes - if that's not ours, then a mutually-beneficial trade could be had.
Draft picks to acquire a higher-ranked receiver, maybe, but I think they've already got something in Jakobi Meyers as long as Dorsett and Gorden are okay. My favorite receiver out there would be Diggs, of course, because of the $$ and skill, but Manny Sanders will now, and always would, fit beautifully in this offense.
Ps. The swings in hyperbole (great thread title, Deus, seriously) aside, this is a great team as is - as good as anyone out there, particularly if Wynn comes back strong. but there are obvious areas of improvement to be found.
