The Mavs Have Spent How Much on Centers?

In Bill Simmons mailbag column from today he had this little line about the Mavericks centers for the last 10 years.

...since Cuban spent $250 million (and counting) on Shawn Bradley, Raef LaFrentz, DeSagana Diop, Erick Dampier and Marcin Gortat these past 10 years...

I knew that all those guys had horrible contracts, but, wow.
