These ratings don't matter. I think most of them are based off the last update to 2k10. As soon as updated rosters come out we'll have more accurate ratings. I can't wait to dominate as the Grizz, Bulls, Warriors and Wizards.
Also another point to note as to how ratings don't matter. I routinely score 20+ points with Shaun Livingston against the Lakers. Ratings don't mean jack.
