WHo wins this one?

I am confident that Carwin can beat lesnar, simply because he is very similar but has better striking and more power. But i am not so sure he can beat Mir, simply because Mir submitted Lesnar first time around. Its a dangerous fight for Shane. The only other top JJ fighter he faced was Gonzaga, and gonzaga didnt use his JJ at all really

Really disappointed the original Lesnar vs Carwin fight had to be postponed due to lesnars bowel obstruction from eating too many raw wilderbeasts.
