They weren't worse than Fall Out Boy.
Why not get some obscure metal acts for next year? NBA fans love shit like Meshuggah

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.
