As to the salary status, what I have is:
Currently Signed (11): $198,261,002
Hold for Draft Pick (1): $2,783,880
Incomplete Roster (1): $2,296,274
Total Assigned Cost: $203,341,156
Expected 2nd Apron: $207,825,000
Space to 2nd Apron: $4,483,844
This is kind of a temporary estimate at best though. The 3 players from last season that this does not include are Horford, Kornet, and Craig. Our only signed bigs right now are Tillman and Queta. There will have to be more moves.
My math has us currently at $15,441,156 over the tax threshold with the pick and incomplete roster accounted for. So now if we dump Simons ($27,678,571), we could be about $12.2M under the tax. At that point, add back in say 3 min contracts and presto, no more repeater. Or say Kornet at $6M and 2 min contracts.
