They need to not make comments about who they think is winning the fight. Commentate on the actual action and forget about scoring.
We don't have this issue in normal sports because they have points to show the winners at the time.
I am sick of sitting there being told "So and So is winning the fight and is up two rounds" and they completely fail to comment on great strikes, etc because they keep going on about it. Comment in the break between rounds and then give me a play by play of the actual fight, not your opinion on the winner. I should be hearing "Double jab from Rob as Izzy slips back and counters with a low kick" or "Rob hit's another takedown, Izzy scrambles and works towards the cage" Not Izzy is winning the fight and Rob needs a finish 10x as he hits a takedown and is catching Izzy. He might be winning, but that isn't when you should mention that. You are ignoring one fighters success and trying to play judge. Commentate the fight, Don't score it.
