During Pea's prime, the one thing he mightve been better than Floyd at was his defensive reflexes, but that's only a maybe. Pea was hard to hit, but Floyd is too and Floyd's defense takes away the opponent's strengths. Pea didn't do that, he overwhelmed opponents with what they couldn't keep up with, but Floyd makes them fight different than theyve fought their whole career the night they meet him, and unlike Pernell, his longevity proves his defense is better. It's not like Floyd never slowed down, but you give him Pernell's decline physically, and I say Floyd's defense still gets him further without a legit L.
The more I thought about this hypothetical matchup over the years, the more Ive been inclined to believe Floyd did handle the seasoned Pernell comfortably. I think it's a bad match for Pernell.
