According to 82games.com, Artest beats his man by an average of 9 points per 48 minutes. Here's how that average stacks up compared to other good NBA players.
better than brand, gasol at PF, LeBron at SG, Francis, wade, odom, dampier, marion, brad miller
same as redd, kobe, pierce, LeBron at PG, iverson, amare, peja, anthony, Dirk
worse than JO, KG, TD , gasol at C, McGrady, Shaq,
where the first group beats thre man by about 5-6, and the last anywhere from 10-17.
Hmm. These are intresting, but don't really mean anything, I think. Something neat to look at. The list could get bigger in each group, but I didn't want to check any more players.
