Tony Allen isnít your average X-factor. Few will be expecting his offensive contribution (10.8 ppg) to rise off the charts. His true value comes on the defensive end . Named to the All-NBA First Team the last two years running, Allen is one of the best perimeter defenders in the league. But he will have to switch his defensive effort to another gear to stop Spursí maestro Tony Parker if the Grizzlies can hope of containing San Antonioís offense. Any rise is scoring will also be a welcome bonus.
