For me, the domestic violence issue has zero relevance. I've known plenty of brilliant people who have fatal flaws, but those flaws have had no bearing on how their genius is expressed. I bet on Paquiao because I believe Manny taps into the passion of his discipline. Floyd is a technician. He's a guys who thinks he can figure out how to win -- as though it's an equation. Manny may lose, but no one will criticize him for not giving it everything he's got. Floyd will likely give it "just enough."
BTW - I bet that someone will be knocked down. I think this fight will have plenty of passion and whether or not Manny knocks out Floyd, I think one of them hits the mat.
