A couple of points:
I'm surprised at Jared Sullinger as the first pick. Everything I've read about him pegs him as a low-ceiling, high-likelihood-of-reaching-it kind of guy - like Paul Millsap, or Patrick Patterson to use a more recent example. Boozer as an absolute best case. Certainly a good player and will produce at the NBA level, but I'm not sure he's worth a top 5 pick - I'd look for him around 8-10.
Kalin Lucas, if healthy, will go early in the second round and may possibly even sneak into the end of the first. He's the heart and soul of one of the best teams in the country over the last few years, he's intelligent, and he can shoot. I see him as similar to Chalmers in a lot of ways: average athlete, a bit undersized, but a pretty good defender, knows how to run an offense, crafty and a good shooter. Kalin is probably better inside the arc, even. But if Chalmers has a place in this league, then so does Lucas.
Brian Williams of Tennessee is one name to keep an eye on going into this year. He'll have every opportunity this year to prove that he can be the alpha dog at the college level, and he is supposedly in the best shape of his life. Depending on how Tennessee does and how he does personally, he's a guy who could get a lot of attention in the coming months.
