He got too much too soon. Lost the hunger and the drive to get better. Also, if we're honest, after his impressive run through 145 including Aldo nothing has been particularly impressive at all since then. His wins against Max, Dustin and Mendes were very good and look better as time goes on. After that? Credit for knocking Aldo cold. But, Aldo lost that fight before the bell even rang. Conor mind fucked him. Eddie Alvarez? Conor probably got lucky that Alvarez got lucky against RDA. Alvarez was tailor made for Conor. Khabib beat him in every facet of the game. Cowboy has been shot for years. Dustin made relatively easy work out of him. Where does he go from here? Diaz makes the most sense. Both in terms of money and a very winnable fight. Lose to Diaz and retire. Win and it has to be impressively and he's on the way to a rebuild. I've probably said this already but I'd go Diaz, Ferguson and then Poirer.
