I think there is a real possibility that teams will run out of guys to sign before they run out of cap room. I think there is cap room out there to pay average players as much as the top of the line free agents used to get, and I think teams will hesitate to do that.
It could really create an impasse in signings. Players will be basing there wants on the money available, and teams will hesitate to blow out the current salary structure.
As an example, lets say we had Warren and Seymour, and not Jarvis green. we need a 3rd DE to backup both of them. Assume we have pretty much handled our other needs, and there really isnt any player on the market that is attractive to us. We have 12 mill in cap room, and the best player available, who is a shadow of Warren and Seymour wants to be paid more than Seymour. One argument is you have the cap room, so you can afford to pay the best guy on the market whatever he wants. (That thinking seemed to be prevalnet throughout the league in the past) But you are buying another problem, where you have raised the bar for every player on your roster, and redefined the salary structure of your team.
That is an extreme example, but when teams have this much cap room available, do they really start paying jags what they used to pay starters, or pay average starters what they used to pay all-pros, just because they can?
I think there are over a dozen teams that could afford to act like the Redskins or worse, but I dont think many, if any will choose to do so.
I would not be shocked at all if many teams leave a lot of cap room on the table this year.
