If we're going to say that we have the best offense in the NFL, then we've got to do better than the average against any defense. Beating up on average or below average teams makes the offense look good, but doesn't mean as much as being below average against teams with better defenses.
Even last year in the opener against the LA Rams, we scored 17 points when our offense was missing only our starting right tackle. I get the feeling the Rams could have scored more than 20 points if needed, but this offense we put together has to be able to score more than 17 in a game like that.
We can't just look at overall scoring numbers, where we blew out some teams with bad defenses, and think our offense is the best. It has to be the best week in and week out. Maybe we don't beat the Rams no matter what last year, but I would have felt a lot better about the offense if it had put up 24-28 points and it had only been the defense that had let the team down.
For comparison sake, the Kansas City Chiefs only had one game last year where they scored fewer than 20 points and they won that game 17-14. Their two losses were 40-32 and 38-21, so it's hard to say their offense let them down. In 2019, the Chiefs lost one game that could be blamed on the offense, 19-13 to Indianapolis. That's what the best offense in the league needs to be.
