So it turns out a lot of huge betting favorites have been losing lately. As a bettor, it only goes to confirm what I have always believed: Betting lines often get out of control and rarely should you bet a fighter at exhorbitant odds. Consider the following: Between May 10 and May 24, we've seen the following upsets: Johnny Eduardo over Eddie Wineland, a -935 favorite Will Brooks over Michael Chandler, a -1000 favorite Mitch Clarke over Al Iaquinta, a -450 favorite TJ Dillashaw over Renan Barao, a -1215 favorite That's one very large favorite and three MASSIVE favorites over the course of three major MMA events. So here's the question I have: Who is it that's continuing to bet these fighters at -600, -700, -800 and beyond, driving the line higher and higher? In a sport as volatile in MMA, why are we seeing odds like this on any fights that aren't total, absolute squash matches? And furthermore, will losses like this teach the betting public a lesson, leading to more conservative approaches and more reasonable betting lines in the long run?
