Some fighters, like Frankie Edgar, don't believe Conor McGregor will ever defend his featherweight title after earning it with his first-round destruction of Jose Aldo back at UFC 194.
That's because "Notorious" is too busy trying to test his skills at welterweight, which ultimately didn't work out his way during his fight in the 170-pound division against Nate Diaz at UFC 196 (see it again here).
So will Conor ever go back down to 145 pounds? According to one of his training partners, Gunnar Nelson, the Irishman could very well defend his title in the coming months, but going through the weight cut is just a "nasty" process for the biggest star on the Ultimate Fighting Championship (UFC) roster.
