I'm sorry, but Frank Mir today is a very different fighter to Frank Mir a few years back. Did you see him destroy Nogueira his fight before last? I'd find it hard to believe Roy would get anywhere close to him.I'd back Roy to beat Mir, he beat Frank in a grappling match a few years back and I think he could do the same in the octagon. Big Country is legit, he hasn't looked it yet but he's just doing enough to get through the early fights un-injured.
