Wouldn't be funny if Vitali can't come out of his corner in between rounds.
First you say size is not why VK will win, then you mention physical attributes and size. Friendly reminder: Adamek also has "skills".
Manny himself predicted Adamek would fall to Golota and look how that worked out. Power is nothing if you can't deliver. My money is on K2 but...
Arreola is clearly "fatter" but not taller than Adamek. They stood eye to eye at the weigh-in and IMO Adamek appeared slightly taller.
