If there is no trade, I would expect it to be either Pruitt or Miles, unfortunately. It's obvious that Brian Scalabrine is the 16th best player on the roster right now, but he also has a contract that will be valuable to a team looking to get under the cap after next year.
And with our lack of size, I don't think it would be a good idea to cut Miles. Versatility is key, and he would be able to defend a couple positions and give Doc some different looks.
In terms of Cassell, I was all for bringing him in last year, as were most of us. But I didn't turn on him like many others (not saying that's a bad thing) after his less than stellar performance in the playoffs. However, when I look at things right now, I think Gabe Pruitt would be more valuable to the team, now and in the future. Sam can't play defense, and even though he's better than House in breaking a press because he has better handle, he's lost a couple steps, which makes him more vulnerable when teams are pressing. Gabe obviously doesn't know the game as well as Sam, but he has the tools to be a lock-down defender at the point guard position, as well as a nice jump shot, great speed and good handle. He belongs in this league, and I believe he's going to grow into a good player. It would be a shame if it weren't here in Boston and we got nothing for him in return.
