QB:
I say re-sign Moore. He's the only QB who actually won us a game last year. I don't want to spend the entire money saved cutting/trading Romo on a backup QB. Rather stay with what we have. I did hear Dak has a great relationship with Sanchez, which is great for Dak's sake, but I never want to see the ball in Sanchez's hands... Who knows. Maybe re-sign both Moore (to backup Dak) and Sanchez (to mentor Dak).
RB:
No one. I'd rather getting a RB in the late rounds of the draft. There are always guys sitting around late in the draft. Seahawks' Alex Collins and Thomas Rawls went in the 5th and undrafted, Dolphins' Ajayi went in the 6th, and the list goes on.
WR:
No one. I want nothing to do with Butler. He's not a winner. Only thing he has going for him is speed. No talent. You can find better guys at the end of the draft. Williams, on the other hand, is frustrating. He disappears for entire games and makes key drops. He'll also probably want more money than he's worth.
TE:
No one. Unless we're expecting Escobar to take a drastic change in the right direction now that Witten is almost done (maybe), we need to move on and try to find our heir to Witten. Maybe the Rico experiment will pan out. Escobar can't even beat out JAGs like Swaim and Hanna.
OL:
Definitely re-sign Cooper if we can get him on the cheap. He'd be excellent depth and could be plugged in as starting LG if we decide to try Collins at RT. I'd love to keep Leary but I could see us moving on to the healthier, younger, cheaper option in Collins. It all depends on if we think Collins an play RT. If he can, then try to re-sign Leary and fallback on Cooper if he's too expensive. If he can't, then move on from Leary and make Collins the future LG.
DT:
No one. We need to improve as a D-line. Jack Crawford seems like a good guy but he shouldn't be one of our top 8 D-linemen. As far as T. McClain goes, he played well next year but I think we need to do something big at DT. We need to either get a stud free agent DT like Sheldon Richardson or Dontari Poe to pair up with Maliek Collins and wreak havoc on the inside, or we need to see if Tyrone Crawford and Collins can make an interior duo. I'd prefer McClain over Thornton but we invested too much money into Thornton to keep both.
DE:
Definitely keep Irving. That doesn't even require an explanation. And who the heck is Ryan Davis? Get rid of him. We also need to improve DE significantly via early and often in the draft, and possibly with a free agent or two. But free agent DEs usually aren't worth the money. The truly great ones don't hit the market until they're used up. Draft DE and sign DT.
LB:
Maybe Gachkar. He seems to be a decent special teams player. He's definitely replaceable if we find someone better or cheaper. Move on from Durant. He's a decent player but he's getting up there in age and we should start seeing what we have in our younger guys J. Smith, D. Wilson and Hitchens. And definitely cut ties with R. McClain. He's less reliable than Gregory.
CB:
I'd re-sign them both. I wouldn't break the bank on either one though. Carr will probably come cheap and he never gets hurt, so I think he's good to have on the roster just in case you're short on CBs. But Carr should definitely lose snaps for the younger guys. We know longer need to make him the starter to justify his contract. He should be our 4th CB. And Claiborne is still young and a beast when healthy. I'm confident we can bring him back for cheap considering his injury issues. If we get rid of Claiborne we'll need to replace him with a pricey free agent or an early draft pick, and I definitely don't want to see us waste early picks and big money on CBs.
S:
Bring them both back if they come cheap. I know the team seems to love Church. I'd rather we didn't get so emotionally attached to players because then we guarantee guys like Church and Free starting jobs for years despite how unexceptional they are. I'd like to see if Wilcox has gotten good enough to be a starting SS. He has way more upside than Church. I'd also like to see what Heath can bring us. He's young, freakishly athletic, and makes plays in his limited chances. If we had to choose between Wilcox and Church, I'd definitely go Wilcox.
