Numbers get tricky when you compare different eras.

Those first 5 you named : Bledsoe, Kreig, Palmer, Testeverde, and Esiason all made either 2, 3, or 4 pro bowls. McNabb made 6. I’m not saying pro bowls alone should be the gauge, but it’s a fairly good indicator of how someone rated at their position in their era.

All that to say: McNabb was clearly better than all those guys.

Making the case for him: one of the best QB’s of his era, numbers are there, no SB’s but consistently very good team success, and he mostly carried those offenses. I’m trying to think of a Hall of fame QB who didn’t have more offensive talent to play with at the skill positions.
