Pondering his next career move, Radio Shack pitchman and former NFL defensive end Howie Long told reporters Monday that he is interested in directing an upcoming installment of the series of commercials in which he playfully endorses high-tech gadgets with actress Teri Hatcher. 'I've given it a lot of thought, and I think I'm ready to get behind the camera,' Long said. 'I've done the acting thing for a while now, and I just feel like it's time for a new challenge.' Long said he could bring the kind of experience and insight to directing the commercials that only comes from having spent countless hours on the set.
