Really weird. 2k10 is definitely strange when it comes to simulating games. I'm not sure how any team with Kobe and Pau or LeBron could be sub .500. I'm a little bit dumbfounded by my own team's struggles, as well, though that could be attributed to the league having more parity.
Would you mind listing the overall, offense and defense ratings of all of the teams in the league, so we can compare the ratings to their records?
