I feel dat but what i'm saying is that why I know Bird would get his because of his skillset I also believe he would struggle a bit with all these athletes in the NBA today. The same way I don't think MJ would run roughshod over the league like he did but he would still probably be the best. It would just be much closer than it was in the 90's.
just because you're "athletic" doesn't mean you impose more of a challenge than "non athletic" players
Playing D is a skill first then it's supplemented by athletic ability.
Look at the best defensive wings over the last 10 years or so.
Bruce Bowen - not athletic at all
Tayshaun Prince - somewhat athletic
Lebron - athletic
Young Kobe - athletic, D slipped as he got older
Tony Allen - athletic, but not a freak of nature, torn his ACL trying to dunk
Ron Artest - somewhat athletic, very strong with quick feet
Andre Igundala - athletic
etc.. etc..
Playing Defense has always been about your skills more so than athleticism
