How valuable is Tim Duncan to the Spurs? Nearly MVP level?
I was just looking at this team, and what he does for this team is probably under rated. Looking at the roster, they're basically the Rockets without him. Which, of course is pretty good, but his defensive impact isn't really being looked at nearly enough. He's dropped off on offense, but he's having his best defensive season in quite a long time. I'd go as far to say that only KG and Dwight are playing better on defense this season.
So while, no he's probably not MVP level, don't underestimate how good this guy is just because he's got mediocre stats.
