Calderon hits like a woman, lets be realistic. The guy throws alot of punches and has great movement but at the end of the night his opponents face rarely if ever has a scratch.
Viloria would stalk Calderon and eventually wear his man out, Viloria hasn't looked to great in recent showings but to be fair Calderon simply doesn't have the power to keep Viloria off his tail.
I'd take Viloria late.
I'll take Shane in a great action packed fight, I don't think Vargas will be able to cope with Shanes speed and if Mosely is able to work his absent combinations he may be able to send Vargas home late in the fight.
Shane UD or late stoppage.
