Way too early to guess on those guys..
If I were to guess..
I would lean more toward Chris Stewart. Stewwy was a bad dude out there tho.. "Fighting wise".
Kostin does have a boxing background!
I know he trained with his cousin when younger.. who was an actual boxer.
He'll definitely have an edge to him, and won't be scared to throw hands!!
Haha so that's good to know..
How much he gets into scraps!?
Will be the question..
Don't know if he's really about that now!?
I'm sure he can hold his own tho..
Edit: Not really sure who'd I'm compare him to skill wise.. he's got good shot, skill set and big body.
Hopefully he can take advantage of that.. Eventually!!
