Reeves is a better track athlete, and it's her first love, from what I hear. She seemed to be pretty good, but I can't fault her for wanting to be happy. Smith is backing up Hunter, and there's another young superstar coming in (or is already here) that will probably jump right into Hunter's spot after she's gone, so Smith isn't going to be getting any more playing time, anyway. Very understandable that she'd want to go somewhere that allows her to play more.
