Ultimately we need someone who can physically guard the dominant swingmen we are going to face in the playoffs. I don't exactly know who that player will be. I can tell you that it's not Eddie House or Gabe Pruitt; so this idea that we can get away with a backcourt of just those two isn't going to work come playoff time. Furthermore, the argument that Pruitt/House is going to play the 2 and someone else is going to play the 3, also isn't going to work, since with Pierce and Ray Allen playing 40 mpg in the playoffs, there will only be time for one backup 2/3.
So I'm not sure if it's someone from a buyout, Walker, Giddens, or even a healthy Tony Allen, but the C's need to find that player by the time the playoffs come.
