I get that, but good teams don't worry about that. They draft their own good players and use FAs to supplement, not build the team. If Poles plays this offseason right, between free agency and the draft he should have his 3T, LB or 2, RT, C/G, and depth at DE and WR at least. They look to already be set at 1 CB position, nickel, safety, LT, RG, have a couple rotational DEs, a pair of solid WRs, TE and a QB. They shouldn't need to hit free agency too hard going forward. Most of those guys will be under contract thru 2024. So, they can afford to spend big on RB. Now all these guys won't work out, but you have subsequent drafts and late picks/lottery tickets that sometimes pan out to fill a hole (Sanborn).
Like everyone talks about Elliott's contract preventing the Cowboys from doing all this stuff, but the only thing it did was cause them to lose Amari Cooper, who they are doing just fine without. They don't need to hit free agency hard because they keep their own guys that matter and draft well. And they perennially are in the playoffs, when Dak is healthy.
