I was OK with the Perkins trade. Danny was not going to give him the big contract that he wanted, so we would have lost him for nothing anyway that summer. I think he was also just coming back from ACL surgery. If you go back and look at the 07-08 season and playoffs, during crunch time (last 7 minutes of the game), it was Posey on the court, not KP. Perkins had a great snarl, but was an average center at best (pre ACL injury). I think Danny figured his best days were behind him, was not worth the investment, than KP went out and proved that in the ensuing years.
I know that there is a lot of love for KP on this board, but that was a good logical trade by Danny. I wish Jeff Green had been more consistent, but the trade made a lot of sense at the time.
