Robertson, it's ironic that you mention Mosley in your post as a common factor. Mosley hit Maywearther with not one, but TWO of his best shots in one round. Mayweather buckled, but his confidence far from disappeared. In fact, he was beating Mosley back by the end of that same said round. I would wager that Mosley hits at least as hard as Manny does (One KO'd Marg, the other didn't, remember). I agree with your sentiment that one punch, especially from Pacquiao, could change the complexion of the fight.
Here's the thing. Roach, I think, seriously had his eyes opened to the fact that regardless of how much work he's done with Pacquiao, movement still troubles him as much as it ever did since his second fight with Marquez. He can still win fights, but doesn't look nearly as convincing doing it. Pacquiao is prone to frustration when hunting a moving target and Roach under no illusion with how close Manny came to losing against Marquez. Mayweather may well be different to Marquez, but the things that Marquez did to give Manny fits (use lateral movement and pop out lead right hand counters), Mayweather does better.
This isn't about "who's fault it is the fight hasn't happened" or "who's the coward (I would never use that word for anyone who steps between those ropes for a living because I wouldn't)". It's Roach sizing up and opponent for his charge, one he's known for years and knows better than any of us. He knew Oscar couldn't pull the trigger anymore, he knew that Mosely was too much about the time he sparked Marg and he knows Mayweather is a stylistic nightmare for Pacquiao (not that Mayweather definitely wins, for all those sensitive types out there). Pacquiao is an exceptional fighter, but "box, move and counter" is like Green K to him.
I wish people would stop taking this all so personally. Be a boxing fan first.
I see where your coming from there, but Im just stating that surely Mosleys comments on Pacs power must have some substance to them? I believe Floyd hit Shane with his best power shots, sure Shane looked wobbely, but he was not floored and genuinely hurt by May, both physcially and mentally.
Yes Floyd will present a nightmare to Pac, and i believe at Pacs age, Roach will have a uphill battle changing Pac entirely for this fight. Floyd will almost certainly fight his usual fight..Duck, avoid and counter, and when attacked or rocked, hold on. I just cannot see Floyd avoiding at least 1 of Mannys left hands, to me, the whole fight depends on Mannys left, and his adjustments, not Floyds
