just think about lebron james, sometimes he plays PF or SF but sometimes he plays point forward!!! he can play all 5 positions cuz of his skill set. in the heat vs pacers series he was guarding 7'3 roy hibbert sometimes

i think skill should determine what position you play for example i look at Kevin Durant who mostley plays SF but if you really had to you can put him at point and run the court and you can put him at PF an pound with the big boys because hes so quick with the ball.

For another example how about Rajon Rondo that dude is a walkn triple double if someone of his height can get 10 rebounds over guys who are litterly twice his size it takes skill and fundamentals not height height is just a subsitute to those who arent fundamentaly sounded
