I like Cain too, but he's had less than 10 fights. C'mon ya'll Fedor is a legend.
Cain is still improving.
I've said this before, and I stand by it. I think Brock Lesnar would give Fedor fits, with his combination of size, strength, athletic and wrestling ability.
He would get owned on the feet, but Brock would take him down of course, and I think he would control the fight.
Let's hope we get to see this one day.
