Tracy McGrady worked out for the Spurs this week and will work out for the Knicks on Thursday, sources tell Yahoo! Sports. T-Mac hasn't been able to find work to date as he's looking for a team willing to guarantee his contract for next season. Interestingly, McGrady may be faced with the decision to either accept a "make-good" contract or take his game overseas, potentially to China. He's going to have to prove his knees can hold up regardless of where he signs.
