I don't even need to see their bodies to know which guy I'd be more afraid of in a bare knuckle contest. edit: it's Robinson.
Walking down a dark alley at night? I'm definitely more afraid of the other guy to stab me while he's tweaked out. edit: it's Kassian
Buddy looks like a nice guy. I doubt he's a particularly great fighter. In the clips above, he seems happy enough (and very capable) to just lock guys down. Except in the 3rd clip with Aulie, who's actually in his weight/height class, and he's a bit pissed off after a hard hit. That looked...painful for Aulie.
I bet most of Robinson's fights come from upstarts trying to prove themselves in the prison yard.
