Floyd is underestimating Conor big time. I smell hubris. I see Floyd overreacting, overextending and being knocked out stiff.
Look at how sloppy he is against Pacquiao ... and that happened a lot of times.

Now this is what happens when you do that against Conor

Conor is younger, bigger, and hits harder than Pacquiao. He is guaranteed to land that counter left hand against a battle-worn 40-year old Floyd. I really doubt he will be able to take this shot without being flatlined. Conor's precision is one of a kind, his movement training made him arguably the most precise puncher in the entire realm of combat sports.

The timing and precision will be Floyd's downfall. Mark my words
