when was Dr J considered a below average defender? I just finished the book Loose Balls, a Verbal History of the ABA and every single person quoted in the book revered Erving for his defensive prowess
as for the ratings issue, Dray vs Klay they are on the same team so we can discount any team centric stats that might be in play and Dray has significantly better Drb, Stl, Blk #s than Klay, and significantly better advanced #s (drtg, dws) than Klay - I think it's a revealing comparison that lays bare what appears to be a flaw in the ratings equation
