Their mistake was giving Perk all that money, but I'm glad they did because I love Perk. He's obviously not worth all that money, but he's a great guy to have on your team on the right money.
Their other mistake was not flipping Westchuck for an All Star center and a decent starting PG when he was at his highest value. Instead, they traded Harden for Kevin Martin and change...
PG/Harden/Durant/Ibaka/AllStar C is a championship team in today's NBA.
OKC should get a better center. If OKC is trying to get Gortat or Asik, I hope the Cs can help them, taking Perk's contract and sending Bass+Crawesome to the Rockets/Suns. OKC would have to give us the Dallas 2014 first rounder (top-20 protected until 2018, then unprotected), and maybe a young reclamation project (PJ3, Orton). It would suck to overpay Perk, but the Dallas pick could be useful, and the SG/PF logjam would be eased once Rondo is back and we don't need Crawesome as our PG. Perk's contract, as terrible as it is, expires in the summer of 2015, becoming a useful piece to trade or to let expire.
