It's all context though. 0% of Ravens fans think the Ravens have won that trade SO FAR, because Stanley didn't play last year, our Tackle play was a joke, and Oweh was just a rookie who was good but unspectacular.
So people that are evaluating that trade NOW would say the Chiefs obviously won it, which is correct.
Whether that holds up for the next 3-5 years, or not, remains to be seen. That's why ignoring people on social media is so great. People just want to be right NOW, because nobody will call them out for being wrong later.
