Last season, Vince Carter and Dirk Nowitzki were teammates in Big D.
While Nowitzki re-signed in Dallas (on a sweetheart deal), Carter jumped ship to Memphis (where he is a great fit). That makes them rivals in the deep West.
The two meet in a preseason game Monday and Carter showed he still has hops as he bounced up and shut down Dirk at the rim. Nice. You know they laughed about it after the game (it is preseason, after all).
