I'll cede the CroCop win. I don't think this would be a gimme' fight for Cormier. Gonzaga is a big HW with skills. Though every fight of Cormier's he impresses me even more. For me, it is just the opposite with Gonzaga.
A win between Cormier vs Gonzaga would definitely have more reward for GG and more risk for Cormier. Different than the Mir fight. I think it would still be a good fight to watch but not as high profile.
