My opinion isn't worth shit tbh. I was gonna post a rant on the random thought thread about this sometime - it's hard to get the nuance of a sport like football if you didn't grow up playing/watching it.
I'm from the UK, and I've always had a passing interest in the NFL, but only really got massively into it when I moved to Baltimore in 2015 and found the perfect team for me - plus there's nothing like live games. Trouble is, I don't know much about strategy, scheme and the nuance of each position. With soccer, I get it; I can look at a team and see the formation, the tactics, who did well/messed up even if it was away from the ball. Same with rugby. With football, I'd have to study to get that depth because I didn't grow up with it, and i don't have time to do that.
I understand team building, I get the mentality, and I can see what the team needs position-wise, but I just can't evaluate players yet because I don't understand exactly how they get their jobs done, and what's a good/bad thing to do. I can only see outcomes (sacks, catches, etc). Maybe I'll learn, but right now I have to lean on people who know what they're talking about.
