The Fighter 'Buzz' List: A Question about it

I'd like to know UGers opinion on how many of the current top 10 on the buzz list would still be there if you replaced it with a top 10 current 'best'.

By best, I mean a combination of best fighter and best ambassador for the sport. Basically, the most worthy.

For those too lazy to click on the buzz list, it's:

1 Kimbo
2 Fedor
3 Gina
4 Kim Couture
5 Roy Nelson
6 Brock Lesnar
7 Bobby Lashley
8 Anderson Silva
9 Mayhem Miller
10 Lyoto Machida

Wat?

 I don't even know on what it's based.  Is Kim Couture really creating a lot of buzz?
