People act like McGregor has been fighting regularly for years..... he hasn't. I don't know how he has his ranking other than helping him maintain his hype for rare matches like this. When any fighter hasn't been practicing their trade regularly for years they will get rusty and not be who they were in their prime, that is where McGregor is at. And Cowboy has been fighting regularly for Many years. This is an easy one to predict, Cowboy will play great defense round one as he does then later in the match a frustrated McGregor will make a mistake and Cowboy will capitalize on it. Though Cerrone lost his last two he is much more raw, ready for a real MMA fight than McGregor.
