Winner!

He looks in the best shape he has in like forever, he really is taking this seriously

Looking at the picture, he may of had 20lbs on him at the weigh-in and come fight time he will have even more but there doesn't look to be a massive difference in size.
I really want
Mir to win but
Lesnar is a beast does he have a good chin, nobody has properly tested it and you cannot make him superb at submission defences in such a short space of time, Mir is on another level in that department.
