Callum Smith beating Eubank Jr is a stretch surely.

Having see Smiths last performance, ostrich neck stuck out for someone to whack off the heads GOT style. Almost as stiff as a brick in his body movements.
Just a grade up from a tomato Can in World Champion terms.

What he can do is ride rough patches with decent pros and come back.

Eubank Jr could go the distance with smith, perhaps mess up his body for a late stoppage at best.
