5.03 Tyson Chandler
When healthy Tyson Chandler is a force to be reckoned with. Athletic and defensive minded, Chandler can bring great defense while also jamming the ball when necessary from Paul. He's long and only 27 years old which gives him a number of years to dominate inside. His defensive rating and defensive win shares are phenomenal for a guy who people don't think much about. He's 14th in defensive rating amongst active players and that list includes 6-ish bigs who are so far past their prime they should all be retired by now. Also puts him above defensive guys like Artest, Smooth, and Okafor (whom he traded places with last season).
I considered briefly taking a forward here, but couldn't quite settle on one in particular who was lights out better than the rest. It really then came down to Elton Brand, who's not big or tough enough to play center for my team, Dalember, and Chandler. Dalembert is a few years older and though in general healthier than Chandler lacks the physical presence in a real game that Chandler does. Blocks as stats don't really indicate that Dally is better defensively than Chandler.
