This is a problem that has plagued many basketball games over the years, they assign stealing and shooting the same button. When you steal the ball you accidentally shoot a half court shot.
I'd have to agree too. Fair enough if you're spamming the steal button but it's annoying when you gain control of the ball unexpectedly and end up accidentally launching a shot from beyond midcourt. All the more reason to allow some more flexibility in customising the controller configuration.
