There were some good fights that were never made. Arlovski, Overeem.....Cain's lucky they never fed him to Carwin.Cain is an all time great. People point to his inactivity and the fact that he's only faced a handful of opponents in the last 5 years without recognizing that there was nobody else with the resume to challenge him at the time.
With regard to his resume he is a victim of circumstance. But anybody who knows anything knows that he's a destroyer.
