ALL the best White QB's get the complexion for the protection card by the majority white mainstream NFL media, not just Allen.
Its Allen, Herbert, Burrow. Even the lesser ones like Goff, Stafford, Cousins, Carr etc
If you're a black QB and you're not god-tier, there's going to be calls and dog whistles by both non-black fans (mostly white) and the white mainstream NFL media for that black QB to be replaced, if that black QB doesn't at least make the Super Bowl.
Dak, Kyler, Tua (he's not even black but his dark skin is enough), Geno Smith, Jalen Hurts. There's been discourse at various points this season either calling for those guys to be replaced or asking the question whether they should be.
Another thing I notice is when they want to replace a black QB, its either with a white QB or with another black QB. The media and fans rarely call for a white QB to be replaced by a black QB.
You don't see white sports analysts ever tear into the likes of Burrow, Herbert or Allen for falling short the same way black sports analysts (and white ones) have no issue tearing into the likes of Lamar (when he was struggling in the playoffs) or Dak.
