depends on the team, after July 2nd his actual salary is 3 mil for a 6 mil cap hit, so for the cheapie GMs out there he's ideal from a cap management pov.
His defensive numbers are very good, and when put on the top 6 he still produces at a decent rate (e.g., his 15 games with Bo and Peason which in hindsight may have been a showcase move).
I do think there's a team roster fit out there, but its more whats coming back the other way. The garbage for garbage ideas are a non-starter. I doubt Aquilini would agree to a major salary retention. So best chance is a cap floor team and maybe a mid-round pick back imo.
