You know I've been thinking about this. For me the ref had two choices: stop the fight or let Usyk finish the fight. Giving Fury a standing count that effectively gave him a 30 second breather then another minute to recover in-between rounds really needs to be looked at.
Draws are very rare in boxing. Scoring works on a 10 point 'must" system so one of the two wins the round. It's a bit sentimental to think that a match can be declared a draw simply because neither of the boxers deserved to lose.
