I’m with phillychuck - I think the future is ok.
Offense: Wentz, Sanders, Dillard, Ertz, Goedert, Johnson, Seumalo, Brooks and Ward (slot) are here for at least the next 2 probably 3 years. That’s a very good start.
Jeffries and Jackson will both be back next year for cap reasons, as will JJAW to see if he can become worthwhile. All three could be gone by 2021. A couple of WRs are a clear draft need. We have plenty of developmental guards so fine in the middle of the line (Seumalo at C) even if Kelce retires. Boston Scott and a cheap FA are fine as backup RB, Josh Perkins is fine for 3rd TE. Need a swing backup tackle. That’s the whole offense Other than backup QB.
Defense is more difficult. Need a couple CBs clearly to replace Mills and Darby who are both UFA and I’d be surprised if they are back. I think the slot is fine with Maddox and LeBlanc and Jones and Douglas each get one more year at least. The line is OK with Malik Jackson (2021 would be the cut year, too much dead money in 2020 to get rid of) and Cox as starting DTs, and they probably need one in the draft or FA, with Rush etc available as the 4th DT. DE is also ok with Graham and Barnett as the starters, and Sweat, Miller Ostman and maybe even resigning Curry again as backups. Gerry and Bradham likely back at LB, and I’d guess they resign KGH and find on more LB in the draft or FA.
So that means the draft (where we have a fair number of extra picks) will be 1-2 CB, 1-2 WR, a G/T, a LB, a developmental QB and maybe a DT - I’d guess 1 big FA splash (they have $37m in cap space) at either CB, DT or maybe WR although with a very deep WR draft I think that’s less likely.
I think we look ok for the future.
