1) By far the Raef trade was my worst - I know that we later traded him for Ratliff who we used to trade for Ray Allen, but I am still not over it. He was owed $50M over 5 years and that was a LOT for the time. His injury history was so blatantly obvious.
2) Brian Scalabrine signing - I am totally over that one, but couldn't believe we would bring in a stiff like Scal for five freakin' years.
3) Trading up to take KO - also totally over this. I wanted Shroeder or Dieng, would have been okay with Giannis (at the time).
Looking back, I apparently don't like low upside white bigs. I'm a 6'5" white guy (tall for the general population), so maybe I lack confidence
