I put a small bet on Carwin. Putting large bets on Heavyweight fights is too much of a gambler's game for me. Nothing is certain when guys can hit that hard. I think Carwin has the edge though. Slightly longer reach, in my opinion more power, and the better wrestling. JDS has the better boxing, is quicker and has better cardio but I'm putting my small bet on Carwin tagging him and putting him to sleep.
