82games.com indicating Amare best defender in the league?

[Bernman]

82games.com is a valuable site, there's not much wrong with their data, just the people who are interpreting it.

Stoudemire's opponent PER is 15.2, which judges him as about an average man-to-man defender (15 is the average NBA PER) actually. Far from among the best in the league. If you look at his on/off court defensive points per 100 possessions, it indicates that he had a positive overall effect on team defense last year. But there were other factors at play manipulating the statistic because Amare missed the final couple of months of the season. Notoriously that's when teams play the worst defense, especially those who are old, and are out of the playoff race (as the Suns were for the final few games at least).

Last year Stoudemire's opponent PER 21.8, which terrible. When health allowed him to play almost the entire season, he had a detrimental overall effect on the team's defense (+5 points per 100 possessions).

AT BEST, 82games.com has judged Amare as a mediocre defender.
