I got the nba 2k11 for the Xbox 360 and its hard to shoot, I got good players missing open easy shoots. Anyone know any tips on shoot.|||Yes! Pause the game, during game play. Go to Settings, then fine Coach Mode settings. Once in Coach Mode settings, find shooting helper, or what ever it is called... Something like that. Turn it on, and after every shot, it will show you how your shot was. If your release was too quick, perfect, or too long.
