Thread title is misleading.
They aren't taking it as far as to say Marvin won. They are just saying 50-45 is a lopsided score that they didn't agree with. This is just licking his wounds after an ass whooping and trying to save a little face.
That said, there is no way you can score round 2 for Marvin, he was outstruck 2-1.
And saying he was winning a round until he was losing (rd3) means he still lost it.
At best you give marvin, maybe, rd1. 49-46 or 50-45, he still got sexually assaulted and dominated.
