Just read some post about Tyson KO's not being impressive.

All big time fighters have many hand picked oppenents. Thats not to say they don't take on and overcome their biggest challenges. And thats also not to say Tyson himself conquered any of his biggest challenges. But to say its not impressive to KO 23 or more professional heavy wieght boxers in the first round isnt impressive is crazy. Alot of them top 10 at the time.

I doubt any other fighter has KO'd 20 opponents in the first round.
