That's just it, these aren't new bugs. Go back and play Celtics versus Lakers for the Genesis, one of the first games EA made, and you see the exact same "magnetic hands" bug. The dunking bug has been present since they switched to 3D models. These are trivial things in the grand scheme of things, and compared to the major AI bugs like never using your bench, inappropriately calling timeouts, mismanaging the shot clock, and the franchise mode that always ends every free agent signing period with half a dozen NBA allstars going totally unsigned, those little glitches probably shouldn't be top priority to fix.
I think people would be more willing to ignore the niggling little issues like that if the big ones were being addressed, but it's just not the case. They keep adding new, often ill-conceived aspects to the game, but they never address the very real flaws that already exist. I think they need to make a hard choice with Live as to where they want it to go.
Either it's a simulatoin, in which case those franchise mode things have to be fixed, the AI has to be spot on. They must get the CBA right, and frankly the franchise mode needs more depth. Or it's an arcade game, and those graphics bugs need to be fixed. In an ideal world they'd put enough developers on it to handle both tasks, but I think everyone's had enough of them resting on their imaginary laurels.
