I don't know how they were during Brock-Chambers, but in recent fights: Liakhovic-Brewster: When Liakhovic was beating the living crap out of Brewster on the ropes, they were saying "wow, Sergei should really watch out now, he's throwing a lot of punches" [Sergei lands 4 flush punches] Other commentator: Yep, see that? He's punching himself out. When the roles were reversed, it was "look at how easy Liakhovic is to hit!" During the first Toney-Peter fight, they were all over Toney's nuts. I was glad to see them being humbled in the rematch. Just some random ones. I don't like them.
The one guy is biased as all ****. But Bernstein is about as fair as you are going to get though he has his favorites as does every boxing fan....
I agree the first toney vs Peter fight they were about as biased as a commentator can get. They might as well have been wearing a james toney T shirt.
