I can't think of a single "record" that he broke that isn't just a sign of the times, outside of ESPN's QBR, which is actually adjusted for time period. Unfortuately QBR only goes back about 10 years, so we have no idea what Marino, Roethlisberger, Manning, etc. would have scored. Every other "record" he broke is simply because of the era he plays in, it would be like saying Steph Curry is a better three point shooter than Larry Bird because he makes more threes in a month than Bird did in a season.
