In Fade's thread on 'the team is in better shape capwise than we think' much of this has been discussed. Mingo, Chancellor, TE- Dickson, Jaron Brown, and possibly Baldwin could now all be candidates for release, which almost immediately creates lots of cap for deals with a few guys to be done. There are other deals which could be advantageously escaped from as well. I don't know if the team will exercise Ifedi's 5th year option, but somehow I doubt it.
I think I have read somewhere that even without the above possible cuts the team is #2 in available cap for reallocation next season. JS has done a brilliant job managing through this cap crisis.
They have money to sign some pass rushers if needed, and to do the deals needed with Wagner and with Reed.
