Floyd mayweather's 1st pro fight: video here!

That was interesting, he was humble and measured, he should have stayed that way.

I think that it is in the Mayweather genes to be able to hit really hard, just like it is in their genes to really hurt their right hands. Roger could kill you with a right hand (and you could kill him with one, ask Rocky Lockridge and Freddie Pendleton and JC Chavez). Jeff Mayweather hardly ever knocked anybody out because he had a deformed claw for a right hand; once he had surgery to get it fixed he knocked out a few guys in a row.
I think that Floyd could ko more guys than he does and that he hits a lot harder than people might think; if he was ever behind in a fight, he'd probably show it. But he picks his spots and fights smart and will probably live to enjoy all his money and remember the good times he'll be having.
