Given some of the arguments you are trying to make, you probably need to take your own advice. Your idea that Peter could pitch a shutout on Tua, is one of the most absurd theories I've ever read on these forums and, on first reading, I couldn't help but think you were joking. Obviously not. And, you're giving others advice to think, rationally? In itself, chuckle-worthy.
See the post above. At what pace did Tua fight at? Against most of his opposition he was a one paced prodded at 5'9 and 250lbs. The only time since he bulked up that he came in shape (against Byrd) he was gassed after 4 rounds. Peter IS durable enough to take what Tua has and he'd outbox him.
So, you've been reduced to using a scenario, in which the best, prime version of Tua isn't allowed to turn up to fight against what you (and some others) consider to be the best, prime version of Peter (Toney II). Not content with that, you've shaved an inch of Tua's height, for good measure (pun intended). I think this might indicate something less than positive about the strength of your argument.
"alt"? Grow up and get real. You lost your credibility when you speculated that Peter "shuts Tua out over 12" (without meaning it as a joke). Assuming you still do actually believe that, then there's little else to be discussed.
Peter needed a rematch to get a proper win over Toney since he deserved to lose the first fight. Why? Because he was easy to land on and Toney took full advantage of that while he lay up against the ropes.. Any guy hittable guy who plods forward is going to get run down by Tua. The fight is a mismatch.
Peter was more formidable than people around here acknowledge, but I think the most likely scenario is that Tua hurts him badly early. Maybe he recovers, maybe he doesn't, but I don't see him winning.
