As a basketball amateur player I can say that all I am concerned about is the fun I'll have playing.
The feeling of scoring or helping your team is everything to me.I feel like I am a part of something really big and I love it.
Now,about those dope shits,I really think that they can do nothing if the opponent really worths it more but still,if somebody's playing unfair to you,you will be satisfyed by returning the favor,even if it means an impossible-to-see kick/punch or shoot in his face.
Beating somebody that plays unfair worths the effort.Try it!
