Take Brees's name out of your mouth! Don't diminish Drew's accomplishments to make a point about Carr. Drew helmed a top five offense year in and year out, nothing "empty" about that. They scored mountains of points to go along with those yards and the lack of rings was purely due to horrendous defenses (like that even needs to be restated).
That said, I agree with you and think Moscanna's take is lame. Put Carr behind an average offensive line and pair him with just an average play caller and things would look different.
