Isn't Hieron more than Hawn can chew this early to his career? Hawn's a judoka with limited standup. I don't see a big strong wrestler like Hieron getting thrown around and losing a decision from his back. Standup wise, Hawn isn't in Hieron's league at this point. I thought he clearly lost to Lyman Good. The thing about Good is he has no power in his strikes. With Hieron, Hawn will be in danger of being KO'ed when he gets tagged.
Personally, I felt Hieron lost to Weedman, but I think that's irrelevant here, since stylistically Hawn can't pose the type of threat to him that Weedman did.
