My offseason plan would be (keeping in mind the Joneses' cheapness in FA):
Re-sign Rush as backup QB, Hoffman as ERFA, Turpin as RFA, Anger as punter, Sieg as LS, Golston as DE, Odighizuwa as DT, Thomas as RFA and Bell as RFA.
Extend Parsons and restructure Lamb and Dak to open up more than $60 million in cap space.
OFFENSE
Try to sign RB Nick Chubb (offer three years, $21 million with $10 million guaranteed; first-year hit would be $5 million, second-year hit $7 million and third $9 million ... or $3.25 million dead cap to cut him.) Alternately, re-sign Rico Dowdle, but because he stayed healthy and had a 1,000-yard season, he will likely cost as much and I'd rather swing for the fences.
Try to sign WR Stefon Diggs (Diggs was on his way to another 1,000-yard season when he got hurt, but should come cheaper because of the injury. I'd offer him an incentive-laden contract: two years, $6 million fully guaranteed with bonuses each years for yards, catches and TDs and possibly Pro Bowl and All-Pro, giving him a chance to earn up to $11 million each year.)
I would do nothing at tight end and only either re-sign Edoga at OL and/or bring in someone the new coaching staff is familiar with to contend with our young players. I would move Guyton to RT to contend with Steele, with Steele being traded if Guyton proves to be as good as Steele or better.
In the draft, I'd take an RB in the second or third round to contend/share carries with Chubb and be there in case Chubb's injury history haunts him.
DEFENSE
I didn't mention him among the FAs we'd retain, but I'd retain Lawrence if he's cheap. Pairing him with Kneeland, Williams, Golston and then Parsons on passing downs would be fairly solid, although I would not be upset with getting another pure pass rusher. I'd re-sign Carl Lawson for that role to keep pass rusher from being as much of a draft priority.
I'd let Eberflus go after a starting LB to pair with Liufua (and Parsons on early downs), possibly E.J. Speed with Overshown possibly sidelined.
I'd bring back CB Stephon Gilmore on a one-year deal similar to what he got in Minnesota (Gilmore played for Eberflus in Indy.) with Diggs possible sidelined. Of course, Gilmore may be considering retirement.
I'd also draft DL with two of our first three picks. I prefer that it be DTs (especially Walter Nolen or Derrick Harmon) and other than an RB or two and a late-round QB, I'd take defense with the rest of our picks, particularly LBs.
My roster would be:
Offense
QB: Prescott, Rush, Draft pick
RB: Chubb, Draft pick, Draft pick (or Vaughn)
FB: Luepke
WR: Lamb, Diggs, Turpin, Mingo, Tolbert, Flournoy
TE: Ferguson, Schoonmaker, Spann-Ford
OL: Richards, Smith, Beebe, Hoffman, Guyton, Steele, Bass, Thomas, Edoga/Free agent, Waletzko
Defense
DE: Lawrence, Kneeland, Williams, Golston, Lawson
DT: Odighizuwa, Smith, Draft pick, Draft pick
LB: Parsons, Speed, Liufau, Draft pick, Draft pick (Overshown)
CB: Bland, Gilmore, Lewis, Carson, Butler, Oruwariye (Diggs)
S: Wilson, Hooker, Bell, Thomas, Draft pick
Special teams
P Anger
K Aubrey
LS Sieg
That's one more than 53, so probably Waletzko would be my cut if everyone was healthy to start the season and Steele held on to the starting RT spot. (Otherwise I'd trade him.) I expect Diggs and Overshown to start on PUP.
I also only have eight draft picks listed and we have 10 (2 DTs, 2 RBs, 2 LB, 1 QB), so I'd either throw a couple of DEs in the mix, a CB, a S or an OL. Probably the DEs because if we don't fix the front, the back end isn't going to matter.
Again, I'm not saying these are the free agents I want (Chubb, Diggs, Speed, Gilmore) but I'm trying to be realistic about what this team would do. I could also see them bringing back Tyron Smith as a backup OT since he's coming off injury. I would have no problem with that, sort of like we did with Jason Peters, as a veteran backup. I'd much rather put Tyron out there in reserve than someone like Edoga. The question is whether Tyron would return for reserve money.
