I find this statement quite ludicrous.
At the time of the trade, Perk was hurt. If we had held onto him, we would've been facing several weeks of Semih Erden, BBD, and an unintegrated Troy Murphy trying to play center. There's no guarantee that would've gone well at all and in all likelihood it wouldn't have.
Second, Perk played 26 mpg. Again, even if we had made no trades and signed the players that we did as FAs, we would've had to integrate the likes of Pavlovic and Murphy, as well as reintegrate that likes of Jermaine O'Neal and Delonte West.
So for Doc to pretend like things would gone super smoothly with Perk here is just plain silly. He's acting like we had a fully healthy, fully integrated 9 man rotation and that we traded away half of it. In reality, we had several holes to fill and we traded away a guy who played roughly half the game at his position.
