Well its not his offense that limits him, it's his striking defense and a chin that's not untouchable.
Mir is not the most powerful quickest or most technical striker and his wrestling/TDs are average. He'll never get Cormier down.
He'll just keep swinging till one of them connects with a big shot and I think that favors Cormier IMO.
