I'm not surprised. Since I saw how stinky was their perimeter, with Moon regressing, Caldy playing hurt and being too conservative and Parker in a scary and quick decline, especially on defense, I thought this would happen. O'Neal is not the player he once was, even when healthy, Bosh disappears in big games when facing elite defenders and an offense that doesn't offer more than pick'n'roll over and over and outside shooting is just too limited when your defense is not elite.
However, in spite of Mitchell's shortcomings, this strikes me as Colangelo covering his ass. He has been making some bad personnel moves for a while. He received a franchise with the 1st pick in the draft and tons of cap space. He's yet to make them more than 1st round fodder and they still have a flawed roster: last season they missed a defensive big to pair with Bosh, this season they miss wings and depth, and I suspect that in 2010 they are going to be missing Bosh.
