How is Overeem even ranked in MMA top tens?

epwar - Everyone is putting him there based off a K-1 win (which has been avenged)! This is the guy to beat Fedor? C'mon! Seriously, how is he ranked in MMA top ten lists when you only look at his MMA record. Lets go back to when he won the Strikeforce title:

*Win Kazuyuki Fujita KO (Knee) K-1 - Dynamite!! Power of Courage 2009 12/31/2009 1 1:15

Not a single top ten opponent in two and a half years but people put him in the top ten???


But it's the same with most of the top 10 ranked fighters, besides the veterans. For example, Valesquez's only big win was against Nog (Yes, his dominance of Kongo is nothing to miminise). For Lesnar it was his victory over the inconstent Mir and his complete dominance of Herring. What propelled Carwin into the top ten was his come back KO of Gonzaga.
