id say this is an actual legit tough question both are pretty bad....i might give a slight edge to small golovkin? i dunno...man this is a brainbuster
Brook pro since 2004. Has faced ONE Top 10 fighter in a 13 year career. ONE. Golovkin, no ATGs on his resume either but his ranking speaks for itself.
Brook has the best single win but GGG has better resume in general. Though it's not a big margin between the two.
