All this "heart of a fighter" stuff in MMA makes me laugh.....give me a break. Brock has participated in collegiate wrestling, pro wrasslin, pro football and mma.....he's done more in under 10 years than most dream of in a lifetime. I'm sure he'll try heavyweight boxing next followed by a brief stint in the rugby capped off with a brief return to pro wrasslin. Shortly thereafter we'll all see the inevitable tv news flash "retired pro wrestler and mma fighter Brock Lesnar was found dead in his Las Vegas hotel room Tuesday morning from what appears to be a painkiller overdose."
