The 2000 minutes thing is weird. I just glanced at the lists and didn't really read his methodology, but it would seem to me that there are a number of players that didn't play 2000 minutes that are overpaid. Maybe he could take out players that didn't attain this number because of injury, but players that are so bad that they couldn't play 2000 minutes should definitely be on the overpaid list.
Overall, the overpaid list looked like it had some pretty good players on it (Carmelo, Gomes, Hamilton, and several more that I can't remember). Like many of you, I agree the methodology is flawed.
