I updated my cap sheets (online version should be up in the next few days).
Here are some quick numbers (000s):
2005 Team Total: $74,350
Less: 52 to end ($7,004)
Deadcap: $16,635

(thx $9MDB)
2005 Cap Total: $83,981
2005 Salary Cap: $85,500
2005 Cap Room: $1,519
Getting rid of Gardner will add another $1.5M, giving us a total of $3M to spend.
For 2006 our total is at $102.5M. I'd expect the 2006 cap to be around $90M.
