Burroughs is like a late-career heavyweight boxer. Doesn't know when to give it up. The biggest advantage during his run was getting BYEs to Final X and the Olympic Trials. His run was over once these three things occurred: (1) Dake committed to 74kg and finally beat him for the 2020 Olympic spot; (2) he moved to 79kg in the early part of the 2024 cycle; (3) he got old.
Mastny’s Russian opponent goes up 10-1 after 2min and promptly gasses. Mastny gets ten exposures in the final minute of the first period to go up 21-10. Picks up a final point on a lost challenge, 22-10.
