I firmly disagree with this notion, it's a tiresome trope hauled out by folks who think Brees is the end all be all (and I love DB).....
Armstead, Ram, Evans, Nicks, Colston, PT, Lance Moore and others were good to great players in their own right, they would have been wherever they wound up.....
They can be great and Brees can be great also, the combination of both obviously was great.....all of this can be true....
