nbaDRAFT.NET has Houston taking Singelton and Brooks. That seems sort of strange to me. I really like Brooks, but the best player on the team is a 28 YO shooting guard and they can't get Courtney Lee any minutes at the position after trading for him last year. ANd while Singelton is a very nice defender to replace Battier, the 3rd best player on the team is a scoring SF. They have a logjam at forward with Budinger, Scola, Patterson, and Hill.
Houston needs someone over 6'10 that can rebound. Chuck Hayes is the best Center-per-inch-of-height in the league, but this team isn't going to contend anytime soon until they have some help in them middle.
ETA - if the Dontaviustomoato Mountrushmore guy who has a buyout problem slides to them at 14 then its a no brainer to take him. The ROckets have so many young prospects that being able to store one in Europe for a couple seasons would be fine. The Rockets have plenty of cap room and 9 rotation players locked up for next year.
ETA2 - all this goes out the window if Thabeet pans out. I'm not holding my breath, but they may already have the big man they need on the roster.
