You have different types of posters here.
You have ones that can evaluate a potential fight based off styles (i.e Dancov, Kev, ect).
Then you have posters that know the deep history of boxing. Personally, my time was the late 80's 'til now. But you have guys that are much older and followed the sport since before the 80's (i.e IronDan, BennySt, ect).
Then you have the trolls that don't know boxing, but solely come here to promote nationalism, racism and quite frankly "stir" other posters up. I won't say names because they know who they are.
When it's all said and done, everyone has their favorite fighters that they speak subjectively on. They're only unbiased in the eyes of someone who's favorite fighter they're advocating. It just depends.
Me, personally, I evaluate guys based on how they assess future fights based on the styles of certain fighters. If they can knowledgeably give me a solid assessment explaining their reasoning for picking Fighter A and then it turns around and plays out exactly like they called it, that makes them a DAMN good knowledgeable poster. I've done this plenty of times myself.
But at the end of the day, the culture in NSB is to increase the rep of the trolls and not acknowledge those that are great fight evaluators. I've seen guys give great evaluations that played out to a T and not one poster give credit where credit was due
