Apparently his MMA credentials are a bit suspect. The last time this story came up someone said he only has 5 fights in his entire career and if I remember correctly 3 of those were against the same guy.
He fought that guy with the 1-11 record 2x, so 2 of that guys 11 losses were to him. He beat him both times in the 2 round, one by armbar and other by TKO from strikes (guy probably wasn't defending good enough). His 1st win was to a guy that was 12-9 and beat him with a rear naked choke in 1st round. That guy lost 8 out of those 9 by being submitted, so fair to say no ground game (1 was Dr. stoppage).
That was what I was trying to imply. Also, that's just how some guys resolve conflict. They fight, then they're buddies again. In college we had a set of boxing gloves/head protection to resolve conflict (I only participated once, then realized getting punched in the head isn't fun).
