yeah its definitely a dilemma because there really arent many guys who can be great refs as fast as the game moves...i do believe the nba refs are the best but it can be virtually impossible to see everything...hell i used to ref a summer league for beer money where guys were up to 6'7" and fairly athletic...there were a lot of times under the hoop where i just called a foul on the guy who looked guilty...so easy to miss shit when there are 6 guys in the paint...needless to say i sucked
frankly the same thing is happening in the nfl...there are some terrible refs but the guys are so fukkin big and fast that its a miracle they get such a high percentage of the bang-bang calls correct
