If golovkin beats brook, where does this rank on his CV?

[Chuckguy]

On saturday night gennady golovkin travels to fight highly rated englishman kell brook, in front of his home fans. Kell brook possesses a 36-0 record,was ring magazine number1 welterweight, and has beaten fighters such as porter and senchenko. If golovkin manages to pull this off and ruins brooks impressive undefeated record, where does brook rank on his CV? Is it better than beating lemiuex or murray? Please discuss...

It all depends on what brook does after. It means crap if you beat per say the number one guy in your division only for that guy to become irrelevant after. Example baldomir was lineal when Floyd beat him but wtf did he do after? Nothing!

his best win but still not worth mentioning. a quality win should not be vs a huge underdog.
