I wonder if being a Russian in America surrounded by tens of thousands of roaring Canelo fans influenced Bivol's decision making during the many interludes when Canelo was languishing on the ropes and unable to even block a jab. That and/or Canelo's tendency to add a little dinner theater acting to set up traps. If so it would be pretty cool to see that something Canelo has been doing for years at the top of his game protect him when he hit the wall.
He hit the wall because Bivol is the figter he`s fought, he`s bigger than Canelo and Floyd and has a longer reach, that combined with his speed was just a bridge too far for Canelo.
