If McGregor fought Nate a 55 it would be a an absolute mis match!! The only thing that saved Nate from brain damage was Mcgregors cardio issues, doubt he has that issue at 55, Nate would leave the octagon on a stretcher, mark my words!!!! Nate is to slow, to pradictable and has no power. Nate should quite while he is ahead a STFU!!!!
