OKC will dump Perkins before they let Durant, Westbrook, Harden or Ibaka go. If they have to they can amnesty Perkins. I don't see anyway they let Ibaka go.
Posts like these are the bane of my existence. So just because they are "way good" players means they wouldn't let them go? "I mean, why would you let Ibaka and Harden go?! HAHAHA, what an idiot!" But, by all means dont crunch the numbers.....
I will for you though, k?
-In 2013/14 season OKC has $33,736,281 committed with Perkins and no Ibaka, Harden or Westbrook (Hoops Hype hasn't taken into account Westbrooks new contract because it needs to know the new salary cap first, I believe).
-I'm going to guestimate Westbrook's first year on the new deal is roughly what Durant's was, which is $16,324,500, which leaves us at $41,583,344 with only 5 guys on the roster at this point.
-Lets say they get Harden to give them a sweetheart/"win one for the gipper" type of deal and he signs for roughly $12mil a year (welllll under market value), at that point we are at $53,583,344 with 6 guys on the roster and no Ibaka yet.
-Moving on; Lets say they also get a sweetheart deal from Ibaka at, say, $8.5 mil (again, these are so low they are laughable, but are illustrating a point that I'm sure will be missed) which gets us to $62,083,344 with 7 men on a 13 man roster.
-At this point it should probably be noted that the salary cap for this season is about $58mil, and its hovered around that for the last 3 seasons. But lets say for argument sake that its at $60mil (that would be the highest in history, I believe) in 2013/14
-Now, lets say they amnesty Perkins like you say they would (eliminating serious front court depth in the process), that leaves them at $53,605,907 with 6 guys under contract.
-They now have $6,394,093 to sign the required 7 players with (meaning each of the 7 will be paid $913,441.....or less).
That is in a scenario in which I gave them an unlikely $2mil extra in cap space and gave them EASILY $4mil off in sweetheart deals per season.
-So lets go the other way and say the cap is still $58mil and they have to sign Ibaka at $11mil and Harden at (still a deal) $14mil.
-That leaves them at $58,105,907 and still needing to sign 7 other players and they are already over the cap.
-Every player they signed would cost them double because they would be paying the $1 for $1 tax up to $5mil over the threshold then it would go to $1.5 per dollar after the first $5mil over. Realistically they would be at the $1.5 per dollar mark because they have 7 more players to sign.
So, outside of "oh my god, who would even NOT re-sign Ibaka and Harden?!?!" this is the real world where things like economics and salaries come into play.
