There are quite a few players from the 70's and 80's that wouldn't be good in this era of basketball. The athletic difference is just too much.
It isn't as acute as it is in football (there aren't a lot of great NFL football players from 40 years ago that could play well in this era) but it is still pretty relevant in NBA discussions.
But players from this era going back would have a much easier transition and would often be a lot better because of the athletic advantage they would have over players from past era. Lebron is freaky athletic for a man his size in today's era. If he had played in the iso-80's, there would have been no way to guard him as no one from that era had the combo of strength and speed to stick with him.
I did say the elites. Wilt would dominate now just like he did in the 60s. I think Dr. J would due just fine. There were great athletes that played in those past eras.
Athletes are more "athletic" these days not due to any evolution of the human body, but due to the advancement of training techniques, medicine, and knowledge. Those "unathletic" players from the 70's and 80's would be a lot more "athletic" in current times.
