Look I am not killing Magic here. I hate the Lakers, but was in tears the day I heard about his HIV (which back then we thought was a death sentence). I love Magic, but he was not a great defender. Read Simmons' pyramid segment on Magic in The Book of Basketball. It isn't that he got lit up by KJ, but it is also lit up by a guy like Sleepy Floyd (in his years with the Rockets) and Doc Rivers. No one (using logic) would doubt that Magic is the greatest point guard ever, but he just isn't the greatest PG.
I just hate the D ratings..Magic should not be in the 90's, and Troy Friggin Murphy should not be a top rated defender - the guy hasn't even made an all-defensive team.
