They weren't worse than Fall Out Boy.
Why not get some obscure metal acts for next year? NBA fans love shit like Meshuggah http://www.youtube.com/watch?v=f1hmI4eqzps
In all seriousness, they need to get some respectable musical acts. Nobody likes Fall Out Boy or Ne-Yo. I literally do not know anybody who likes either of them. I bet at least 80% of the TV audience changed the channel or left the room when they took the stage.
