Prior to signing with San Antonio, he really hadn't put up especially impressive numbers. But he experienced a breakout of sorts with the Austin Toros of the D-League in the 2007-2008 season, averaging 16.8 points, 8 rebounds, and 1.7 blocks. In fact, he led the Toros to the D-League Finals, where they lost to Idaho.
Unfortunately, Mahinmi suffered a severe ankle injury in 2008 and missed the entire 2008-09 season. In 2009-10, he appeared in 26 games for the Spurs, averaging just six minutes a game. In the offseason, he signed with Dallas, and last season he averaged eight minutes a game for the Mavs.
So, all in all, the 6-11 Mahinmi is a bit of a mystery man. Somewhat of a late bloomer who preferred soccer as a young kid, his 2007-08 numbers offer some promise. And with Tyson Chandler leaving town and Brendan Haywood not exactly tearing it up, he has a chance to establish himself as a legitimate NBA player. Whether he will remains to be seen, but he is definitely worth monitoring or even stashing if you have the space.
