After last season, you could say that the entire Grizzlies roster is a Spurs-killer. If Memphis survives a fascinating first-round match up against the Clippers, they pose a legitimate threat to the Spurs in the second round. Despite San Antonio’s sweep of the Grizzles during the regular-season, Memphis is healthy for the first time all year. Marc Gasol and Zach Randolph will have to be at their best; pounding the Spurs in the lane was what propelled them to last spring’s first-round upset. Although the Spurs have turned their aging squad into offensive juggernauts this season, they’ve been one of the league’s poorest defensive teams against guards. That’s where O.J. Mayo, Rudy Gay and the acquisition of Gilbert Arenas will come into focus. Arenas has remade himself into a catch-and-shoot player off the ball and the Grizzlies have been better with him on the floor, which only spells trouble for the top teams in the West. If Arenas gets hot, there’s not stopping him.
