Yes, an yards do matter. Scoring/points can be heavily influenced by your defense, as we saw in 2018. You can't just look at points - or yards - nothing is that simple all these things play off each other. Yards means your moving the ball, which means you're helping your defense with field position and TOP. Everything requires context, even my "bottom third" marker needs some context if it's not clearly representative of actual performance. But generally speaking, yea, if Nagy can't get this offense into even the top 2/3 of the league after 4 years? He should be fired. That is an extraordinarily low bar, like I'm kind of embarrassed by how low a bar that is. We should be expecting an offensive minded HC to be driving us to a Top 10 offense year in and year out. When Lovie was our defensive minded HC, he drove us to a Top 10 defense year in and year out - this shouldn't be any different.
And, before you think I'm being negative here - I expect him to do it! I think he finally has the pieces he needs to run his offense, I'm really excited to see it.
