Eddie could lose in that shark tank to just about anyone in the top five. The division is the toughest in MMA in my opinion and Alvarez is known to WAR too much and fight foolishly in the past, so I could see it.
That said, Eddie has apparently begun to plan more, fight intelligently with gameplans and be more defensive minded after his Cerrone loss.
None of this is a knock on Eddie. He's a warrior and I love the fact that he finally got a UFC title. He's been entertaining us for a decade or so with reckless abandon.
And no, I don't see Duffy beating him.
