Alexander's trunks were ridiculous, why is that allowed, shouldn't ODLH be the only one to get away with it?

Anyway, I thought Alexander seemed a bit mentally weak to be honest, he just wasn't willing to really go for the win. Look at the last round, he was talking about being exhausted although he didn't look extraordinarily tired, but he just didn't go for it. Maybe I'm wrong about him and he really was just too tired to do anything, if so that's not really a good excuse when you're only going five rounds. When he threw punches he did fine, Soliman's the sloppiest fighter I've ever seen, seems like a great guy but still he's so sloppy.
