There seems to be a fair degree of difference on the broadcast/location. Specifically I remember seeing an Alabama game last year on ESPNHD that looked awful, earlier this season I saw one on ESPNHD and it looked fantastic.
For some reason, games at MSG usually look outstanding. Surprising because MSG is a cave once you get above the 200's. Maybe they get good trucks because usually there are mini tournaments/invitationals played there(Coaches/Cancer, Jimmy V, pre/post NIT, Big East Tourney, etc etc).
