Last night's fourth quarter convinced me that of all the bigs other than KG, Doc trusts Sullinger the most to do what he wants.
At one point early in a possession, Sullinger got the ball 20 feet from the basket with his man playing way back in the paint and he jacked up the shot and missed. With most rookies or young players, Doc instantly pulls them and lectures them about quality shot selection, ball movement, playing within themselves and to not play hero ball.
Instead, he let him stay in the game all through the fourth until he fouled out. Sully's fouls being called against him were fairly bogus and the more playing time he gets and more familiarity he gets with the refs, the less the refs will call those fouls on him. He's obviously getting the rookie treatment from the refs right now.
But as the C's were coming back, the lineup Doc went with, for the most part was Rondo, Terry/Bradley, Pierce, Sullinger and KG.
The kid is playing very well, extremely smart, and hard nosed. He is their best rebounder by far. And his understanding of how to guard bigger men and where to be in this defense is exceptional for a 20 year old rookie.
Sullinger is going to start being on the floor during the games most important times. That's going to make Green and Bass expendable and Bradley's addition will make Lee expendable. When the time comes where they are eligible to be traded, I say watch for trades involving those three players.
