I of course disagree. Dan’s passing ability was just on a different level. Even Brady would say that. Anyone who has witnessed Dan throw stands in awe–the velocity that he generated and accuracy that he maintained with just a “flick” of his arm. His passes broke bones in his receiver’s hands! And he did make a number of mediocre receivers look great. And he changed the way defense is played in the NFL, with a passing attack that had a potency noone had ever witnessed.
All of that being said, I certainly understand the distinction between “greatest passer” and “greatest QB” and understand the case for Dan being the former, but not the latter.
