DALLAS, TX - FEBRUARY 20: Dirk Nowitzki #41 of the Dallas Mavericks takes a shot against Chris Wilcox #44 of the Boston Celtics at American Airlines Center on February 20, 2012 in Dallas, Texas.

The Mavericks star passed the Hall of Fame center in a game against the Celtics, a franchise Parrish won three championships with.
Dirk, who passed Parrish with a mid-range jumper in the first quarter of Dallas' 89-73 victory over Boston, is now No. 20 on the all-time list with 23,335 points.
By the end of the year, Dirk will likely have passed two of the greatest PF's of all-time -- Kevin Garnett (No. 19), who is only 350 points ahead of Nowitzki and averages 8 fewer points a game and Charles Barkley (No. 18), who finished his career with 23, 757 points.
And while many of his contemporaries, like Garnett and Tim Duncan, whom he also passed this year, have begun to slow down, Dirk's game is built around two factors -- height and shooting ability -- unaffected by age.
He also reached another milestone against Boston when he blocked his 1,000th career shot, joining Cliff Robinson as Rasheed Wallace as one of three players in NBA history to reach four-figures in blocks and three-pointers made.
