I hear that....he came in the UFC a bright eyed bushy tailed kid, full of life, laugh and like a kid in a candy store. Not only does he look different/more worn out, it seems like the game, and all that goes with it, is exhausting him. The weight cuts/weigh ins have gotten progressively worse and worse. He went from looking a healthy 145 to eyes sunk in, totally meth-head dehydrated, Christain Bale in 'The Machinist' like.
I knew one guy that had confidence like McGregor once....he wa an incredible, incredible musician, charismatic beyond belief, very polarizing, cocky as hell and captivated everyone. He was super succesful for a few years and then spiraled, ended up on crack and broke. I'm not sure if anything similar will happen to McGregor but his life movie will either end up an inspirational drama film or a greek tradegy like morality tale....Im sure in 50+hrs from now we will have a better idea.
