Floyd's chin part 2

[Unknowndonor]

Mayweather WAS knocked down in that fight

He was off balance, but I agree it was a knockdown, but not because of being hurt on that one. However that right hook stunned him in the 4th.

Yes. Zab rocked him, but never had him in serious trouble. On the other hand, Floyd wore him down rnds 5-10 with body shots that had Zab fighting defensive, and was doing alot more damage than Zab did in the whole fight. Then, Zab gets desparate, not wanting to get KOd again, and you know the rest.
