When literally every advanced metrics suggest that the veteran player contributed significantly more to winning than the rookie, your argument to support your opinion is pretty weak. Metrics alone or eye test alone are not end all be all but you seem to be the only one that only use eye test alone and completely disregard all the metrics that unanimously indicate literally the opposite what you are arguing. When your argument is basically that advanced metrics are completely wrong, you have so weak argument that you are not in a position to claim people disagreeing with you are either trolling or too much emotionally tied to their opinions.
Ive used the words "trolling" and "emotionally tied to" to describe posts that say things like "you know damn well that Green is one of the best defensive players in the game" and "quit being stubborn". Im not using that phrasing to respond to arguments based on advanced metrics in general. I'm accustomed to using statistics and results of studies in arguments outside of basketball, so I get what you mean when you say I have a weak argument. I dont get the same satisfied feeling when I have to use an eye test versus citing a study when arguing a different topic. I dont think that advanced stats can be applied to basketball arguments with the same degree of credibility as can the citation of empirically collected data to things that are not sports.
I think there is a good reason why I very rarely, if ever, hear former NBA players talk about advanced stats. They dont do it in interviews. Player analysts dont talk about them much at all. The same with coaches. Mike
Krzyzewski doesnt praise or covet players because of their advanced stats. Most of the analysis being done on individual players is based on qualitative observations. Im not a former NBA player, but I'm doing the same thing. It's not to say that advanced stats are meaningless, but to use them as though the argument that they support cant be disputed is a fallacy. everyone should be able to see that.
I watch Bagley and Siakam play. I look at how skilled i percieve them to be, their strengths and weaknesses, how theyre used, how they affect their teammates on the floor, how they affect their opponents on the floor, how their teams and opposing teams adapt their coaching schemes, and I come away believing my eyes when they tell me Bagley is the better player, right now.
