Remember when people thought Pacquiao was faster than Floyd until they got in the ring and we saw clearly who was faster. Floyd is quicker than Khan.
Why do the Lomasexuals have to bring up Loma in this thread. Marcus Antonius was not aware you suffered from this affliction.
Mayweather does throw faster combinations and he has proved it against far better opposition too. Khan would hop in with predictable one twos impressively for 2 rounds and from round 3 onwards he starts getting caught and if it's not the canvas for him, it's faking low blows to get the heck out.
Zab was actually faster than pbf and could beat him to the punch and counter him, khan isn't and can't. Khan isn't as explosive as zab.
