Wow, you just clearly showed how ignorant you are.
These guys are allowed to flourish in a UFC LW division barely dripping with any talent. If Sanchez hadn't have moved down the division might have died a slow death after the Penn/Florian fight.
The likes of Maynard and Guida are anti-fighters.
Sherk is a reformed anti-fighter, now parading as an crap amatuer kick-boxer, if that.
Edgar has some talent, though would get eaten up in Japan.
