this shows you dont get what we are talking about. any player can go in to any gym in america and if the rims are 10' you are going to shoot the same, the home court advantage is about the ATMOSPHERE not the damn hoops/rims. Hell go watch a practice in a big gym and half the time they have 8-10 portable hoops up there in different locations than the main floor. Kids grow up playing all over the country, in different gyms/courts, they can shoot well in all of them.
Matter of fact, the gym that I shot the best in for my career was our biggest rivals. Maybe I just got up for the game a little more since they always had great crowds but tournament MVP, 10 3's in a game there (out of 14), carrer average over 25 a game there and the only times I ever shot in that gym were on game days.
