My thoughts on the video:
1) People need to understand before a fight, emotions are running high in both camps. There can be a lot of tension and the smallest thing will start a fight. It's not just the fighters who get emotional, but sometimes the teams as well. I remember in the recent Tyson Fury vs Steve Cunningham fight, after Fury knocked Cunningham out, several members of Cunningham's team were being very rude to Tsyon before and after the fight (almost seemed like they were trying to assault him after the fight). There is a press conference video at a restaurant in NYC, where you can see members of Cunningham's team acting inappropriately and almost threatening Fury. This kind of thing is common in boxing. Also, currently, in the Froch vs Groves fight that is happening this weekend, there is a lot of bad blood and you can feel the tension just looking at both guys.
2) I think Latinos for the most part can be great people and very friendly to whites. I don't think race played a role in the man kicking Freddy. More probably it had to do with just the fact that before a fight, there is a lot of tension. Freddy made things worse by walking up to them, by the way (in fairness, the Latinos were acting inappropriately by swearing at him and then kicking him). I think both sides acted wrongly, but of course, Rios's team should be punished because that is assault. Many white-on-white fights also have these kind of brawls. This thing is commonplace in boxing and has to do with emotions running high before a fight.
3) Roach is a former professional boxer who knows how to fight, and although he now has Parkinson's disease and is somewhat disabled, I'd bet money in a 1-on-1 fight he destroys both of these two Latino guys that were "brawling" with him (the one guy who kicked him, and the second, fatter guy who kept saying "Get the **** out of here"). Roach is a former pro fighter and he knows how to handle himself very well.
4) If Pacquiao is the same fighter he used to be, he will absolutely destroy Rios. The Pacquaio of 2007/2008 would stop Rios within 4 rounds. It would be a mismatch. Rios literally has no defense, he's just walking forward, looking for big shots leaving himself wide, wide, wide open. He is asking to be hit. The only reason he hasn't already been knocked out is because he hasn't really fought top level opposition yet. Rios has the 1 decision loss to Alvarado, but really, also had 2 or 3 fights where he should have lost but was given a gift decision. The thing which makes this fight interesting is that Pacquiao is getting older, and coming off a KO loss, sometimes that can change a fighter. We don't know how much Pacquiao has left and if he can still do it.
5) I'll be cheering for Pacman to pull the win, as I'm not a fan of Rios or his lowlife team. I am a supporter of Latinos provided they are proper-acting (Gabe Rosado, Josesito Lopez, Saul Alvarez, Robert Guerrero, JM Marquez, Fernando Montiel, Mike Alvarado are great examples). Latinos are great people, for the most part!
