NFL = Better body/muscle mass, less skill

NBA = More spread out athleticism and skill

Depends on what area of athleticism you are looking at. The best NFL players have the athleticism to be in the NBA if only they had the skills. Football is a lower skill level sport so you can def see some NBA players take on the NFL but only in certain positions, other places they would get eaten up.

Duncan, anyone who says Kobe is just because they like him and look to ignore the facts
