I'm thinking Ben Askren. I just put down 4u or so on him at +115. I think these odds are good for him. Hornbuckle probably won't submit him. He isn't the same calibre of athlete. I remember hearing somewhere that Hornbuckle never really tries to stop the takedown(likes fighting off back). I don't know if thats true but his body is skinny as hell so he's prob going to get taken down anyway. Askren can hold him down
I'm watching hornbuckle-pyle now and hornbuckle is obv tough as hell..I doubt askren can ko him.
Horn could ko askren, either can submit the other one..
I'm leaning toward Askren in the grappling credentials. They are both purple belts in BJJ, just askren is also an olympic wrestler.
Probably a top control dec for askren or a submission win for askren. Only way for Hornbuckle to win is to either Ko him or beat him on the feat in ALL three rounds.
