After the Margarito loss Cintron's marketability fell drastically, especially when Margarito was somewhat exposed by Paul Williams.

Cintron was an accomplished high school wrestler, was offered full ride scholarships to Wisconsin and Ohio State, and has been working on transitioning to MMA for over a year now.

He's got a huge punch.
I don't think all boxers would transition well to mma (even given extensive ground training), but with his power, Kermit's definitely one of them.

Last year's PPV numbers had UFC shows over most boxing shows.
I believe this year boxing numbers have been on an upswing.
