the last round before the doctors called it, watch Masvidal get up and how heavy he is breathing, he cant even catch his breath for few minutes after the fight has been called...There wasnt a point at which Nate was doing something specific beyond trying to keep the pressure or a high pace, but Nate has never been a fast starter, the championship rounds are always key for all his wins and fights, yes he has lost 5 round fights, but the championship rounds are what fit his heavy pressure light power punches style.
Anyone who has avg cardio vs Nate will struggle, no matter their striking credentials, and that is the point that is being brought up, not that Nate was going to somehow karate kick Masvidal into another universe, but the momentum would of probably start to change and the fight would of looked a lot more competitive. It ended cuz of an idiotic doctor stoppage, and yes Nate was losing by a big margin, but being able to watch those last 2 rounds and see if Masvidal could have finished Nate, or what Nate could have done to try to turn it around, im sure those last 2 rounds would of been very entertaining.
