I think there's value on Kenney at +2xx. Dunno how anyone could back Borg as a steep-ish favorite after missing weight a class above and all the personal issues and injuries hes been going through. Don't call me cold hearted, I follow Borg on Twitter and his story is heartbreaking as fuck but at the end of the day I'm about value and that's where I see it.
Kenney is a decent wrestler and his style kinda mirrors the folk style we see be extremely successful in mma. I think it translates well. Gillespie, DC, Askren to name of a few users of this style. Kenney stands out in control, rides, and mat returns to me. I think his fight against Brandon Royval is a good indicator of this where he basically rode the dude for 25 minutes.
I think Casey is the more opposing man in the cage and a better finisher. I see a lot to like about +2xx.
