In the 80's-90's players still smoked, go watch a game...they were soo slow, the athletes now a days would dominate any of the players from that era

This is the stupidest argument in the history of stupid arguments. It actually makes the "Robert Horry argument" look intelligent by comparison. I mean, I'm amazed you were able to stop licking the window long enough to type this.
If today's players were in the 80's and 90's, they'd be doing the same things that players were back then. They'd also only have access to the same training techniques and supplements that the players back then had. So they would be no better and possibly worse than the players back then.
If players from the 80's and 90's had access to the same training techniques and supplements that players today have...Guess what? They'd use them and would be just as great in this era.
Also, if today's players are so much better, why do they need so much more rest?
