Costas stirred up a hornet's nest Sunday with a halftime commentary about Kansas City Chiefs player Jovan Belcher's murdering his girlfriend (and the mother of his child), followed by his own suicide. "If Jovan Belcher didn't possess a gun," Costas told a TV audience of more than 20 million, "he and Kasandra Perkins would both be alive today." (AP Photo/Tony Avelar, File)
