I'd pick Floyd of 2007-2011 or so to beat GGG. The problem is it would take a LOT of moving, and I don't think Floyd has the legs for it anymore.

But yeah if Floyd were to fight GGG in September at 154 (like GGG claims he will drop down to) and wins, people will say GGG was weight drained and Floyd was a coward to not fight him at 160. If he fought and beat GGG at 160, people would say "ohh GGG was overrated, he never fought anyone, he looked flawed and vulnerable at times, he wasn't great, Floyd never fights great fighters in their prime, ect".

If people want to believe something really badly, they're going to believe it and they'll do as much mental gymnastics as needed to justify it, facts/evidence/logic be damned. Most people hate Floyd and therefore want to believe that he's nothing special and has built his career by fighting all stiffs and guys who were picked at their most vulnerable time/weight/ect. These people are not just going to abandon those beliefs because it would invalidate the 10 years or so they've been spouting it to anyone who would listen. Not saying all Floyd's non-fans are like that, but I do see an awful lot of it on this board.

If Floyd fought Wladimir in September and knocked him out, a few people here would say it was bullshit because Wlad was old with a glass jaw.
