Who should the Dallas Mavericks draft on June 28, 2007?

I am a huge Dallas Mavericks fan and I can see that they need much better inside play from the forwards and center. I also see that they need better athletes off the bench. The Mavericks need, more than anything, toughness. The player I would love for them to draft would be Sean Williams from Boston College. He is a behavior problem but I think Avery can help him in this area. I also like forward Glenn Davis of LSU and point guard Dominic James of Marquette. The Mavs draft only in the second round currently, but they have three picks in the second: No. 34, No. 50, No. 60.
