I thought Shane sounded fine there, I have seen him slur in interviews where he looked more like he was drunk. Could be Shane had a few to many when he was interviewed on FNF's.
He didn't look good on that vid either. But I get when your saying... Although he did say Floyd has the power to hurt mayweather in that video... But I think if you have any speech impairment its time to hang them up. It usually gets worse as you get older.
Any chance he was just drunk? Roger Mayweather sounded really bad the last time I saw him on FNF. Could be they hang out sipping drinks while they watch the fights.
I think whether or not Mayweather can hurt Pacquiao is a HUGE factor in this fight. If he can, that puts so much more control in Floyd's hands. If he can't, Pacquiao is going to be relentless without any fear of being knocked out. Can he? I really don't think so. Despite popular belief, Pacquiao can still take hard hitters. He hook Margarito's and Cotto's best punches to the chin. Marquez caught him with the perfect punch, but lightening like that usually doesn't strike in the same place twice. It's what Kellerman said, ever since the knockout...guys believe they can go in and now knock Pacquiao out which is stupid. Maybe there are a few guys out there that can knock him out, like a Gennady...but Mayweather? I don't think he's one of them. Pacquiao's chin is severely underrated after that knockout. Reminds me of what he said in a recent interview, "Mayweather is claiming is #1 P4P. I want to feel the punches of number #1 P4P." If he knows his chin is less than what it is, I don't think he'd be eager in wanting Mayweather to punch him. He wants Mayweather to try and hurt him. He WANTS to feel his power. That's that tiger we all know. This guy can still take hard, hard punches. I truly believe that.
You forget that Manny was also knocked out with one punch by Medgoen Singsurat at flyweight and that wasn't a perfect punch. Manny has a good chin, 64 fights and only three knockouts but he's not Jake LaMotta or George Chuvalo. Personally, I think he might have over trained and got dinged up in sparring before the Marquez fight. Probably, the same thing happened years ago before he fought Singsurat. He was also fighting in that wild exciting trade a punch for a punch style of his early career against Marquez instead of the more cautious angles and traps style he developed under Roach later.
