Cain never fights he is the Abou Diaby ( former Arsenal FC player) of MMA. Who knows how he is going to look, he hasn't fought for about 2.5 years and is mid 30's I think.
https://i.stack.imgur.com/nGMrD.gif Honestly, I think all the time away will have hindered Cain, and for that reason I think Ngannou irons him out; but, as you say, there's no telling how Cain will look, which is the biggest point of intruige heading into this. One could be forgiven for thinking someone high up within UFC doesn't like Velasquez very much for him to be offered a fight with a beast like Ngannou in his first fight back.
Yup. Recall his first fight under USADA testing though. The one in Mexico City vs Werdum. Who would have thought he would gas in one round and have less in the tank than the ancient Brazilian? Seems those P.E.D. accusations the one guy was throwing his way were likely true. You don't go from having a full fight engine, to a one round gas tank, unless you were juicing. Even at altitude, he should have had more in the tank than that.
