Nice to see the Blazers aren't the only ones overpaying for role players under the new CBA. And make no mistake about it, that's what Ibaka is - a role player. The guy averages 9.1 pts/g and 7.5 reb/g and he gets a $50 million contract (latest word is it's $49 million guaranteed, and up to $51.5 million with incentives). He blocks a lot of shots, but that's really all he does. He can't guard bigger (either taller, or stronger) players in the post. Aldridge destroys him head-to-head. So, OKC has to put Perkins on Aldridge. That worked fine when Ibaka got to guard Camby or Joel, but in the last game against OKC, Hickson lit up Ibaka for 21 points on 9 - 10 shooting.
As mentioned above, resigning Harden will likely mean OKC will be at the luxury tax threshold with just their top five players in 2013-14 when Ibaka's and Harden's extensions would kick in. And the luxury tax penalties are MUCH higher under the new CBA. $10 million over the threshold = $2.50 for every $1.00 over. $15 million over = $3.25 penalty for every $1.00 over. Given that they will have another 10 roster spots to fill, extending both Harden and Ibaka could end up costing Clay Bennett and Aubrey McClendon nearly $200 million in luxury tax penalties over the 4 year length of those contract extensions. Personally, I'm all for anything that hits Bennett and McClendon in the wallet.
Of course, they can always save some money by dumping other players (like Perkins and Sefalosha), but that could weaken them on the court (at least on the defensive end) as they try to find cheap replacements for those guys.
