His last move of getting his opponent to come down in weight, and then not even making weight himself was pretty stupid/cowardly of him.
In all seriousness though, you guys are funny. Anytime something even remotely close to Broner/Mayweather is mentioned, you're all quick to flip your lids. There's a worrying paranoia with y'all.
He's a lot of things but a "coward" is definitely unfair. He's moved up and fighting one of, if not, the top guy at lightweight. Don't forget, he's only 23.
