I don't know if you're being sarcastic or not but I'm just going to emphasize that he barely got touched.
I'd also like to add that Randy Couture and walker are a year apart and herschel is in at least as good shape as randy is if not better.
Maybe Herschel has more realistic expectations of himself. Maybe he's got nothing to prove. If he got beat the way Brock beat Couture I'd understand him taking a year off. But in this case, with this specific fight, I don't see waiting a YEAR as justification.
