So after the Bayless for Lee swap let's look at where the Celtics stand for next off season regarding their salary.(all numbers from shamsports.com)
Rajon Rondo $12,909,091
Gerald Wallace $10,105,855
Jeff Green $9,200,000
Brandon Bass $6,900,000
Vitor Faverani $2,090,000
Kelly Olynyk $2,075,760
Jared Sullinger $1,424,520
That's 7 totally guaranteed contracts totaling $44,705,226
If every other non-guaranteed contract was let go and every free agents renounced the Celtics cap number would stand at approximately:
Guaranteed contracts: $44,705,226
Empty player slots holds: 3 x $507,336 = $1,522,008
First round pick holds: +/- $4,000,000(taking holds for the 7th and 16th positions this number could fluctuate greatly if the C's get a top 3 pick)
Total salary: $50,227,234
Assuming a salary cap of about $58 million that leaves a total salary cap space after this trade of a little less than $8 million or
Keith Bogans $5,285,817
Phil Pressey $816,482
Are both non-guaranteed contracts. I think its safe to say Bogans is history but Pressey might stick around another year. If he does that adds $816,482 to the guaranteed salary and eliminates an empty salary slot hold of $507,336 for a total change of salary to $50,536,380 which really doesn't change our available salary under the cap much.
Now the following players have cap holds because they are free agents
Kris Humphries $18,000,000
Avery Bradley $6,278,580
Jordan Crawford $5,406,048
Jerryd Bayless $4,075,500
MarShon Brooks $2,179,354
I think its fairly certain to say that Humphries, Bayless and Brooks would be certainties to be renounced if the Celtics decide to try to stay under or close to as possible the cap. Bradley and Crawford could be offered qualifying offers and if they do then their cap holds stay until they sign a contract with another team, sign a multi-year contract with the Celtics or accept the qualifying offer and sign that one year deal with the Celtics.
Either way, offering a qualifying offer to either Bradley or Crawford or both takes the Celtics out of the running for any type of free agent over the MLE next year.
Now,of course, the situation is fluid. Trades will change this. The Celtics' draft positioning will change this. Their decision on who to renounce will change this(remember they can just as easily not renounce any of the free agents' rights and then sign and trade them) but as of right now, it looks pretty much like major free agent money will not be a part of the Celtic's next year without a team signing and trading that free agent to the Celtics.
