Biggest issue for everyone on here is defense. Those guys could blow by anyone because of quickness and length and for the ones thay may lack quickness, their size won't let you interfere with their destination. Mainly the "tweeners" in the NBA that are a mix of small/ power forward.
I think people would be surprised how effortless it is for them to dunk on you when in your mind, they are too far from the basket to do that.
I am not a real big fan of the current NBA, but as far as pound for pound pure athleticism, there is nothing else like it.
