IMO, one thing that stands out to me when comparing passer ratings is that "average" yearly passer ratings include not only the best, but the worst. Well, if a QB is supposed to be one of, if not, the best should we see what the average passer rating is for the top 10? For example...in 2001 the average passer rating was 78.5. However, out of the top 10 QB's that year, the average was 90. Was Brady's 85 that year really that good? Just like this year. The average passer rating may be 91, but what do the top 10 QB's average? They average 106. Brady's 94 is not good in comparison...especially if we are to consider him "elite". In 2018, Brady had a 97...the top 10 QB's averaged 106. Again, not good in comparison. Now, maybe @cbrad can point out why looking at it this way is no good, but I think it's a good way to look at who is really the top QB's in the league in any particular year.
