LAS VEGAS—It’s called Dana White’s Contender Series, but Mick Maynard made one UFC contract offer on Tuesday. At Dana White’s Contender Series 73 , White wasn’t all that impressed by light heavyweight Kevin Christian , who defeated Francesco Mazzeo by second-round triangle armbar . It was Maynard who convinced White not to pass on the 6-foot-7 Christian (9-2 MMA, 0-0 UFC)
