I guess specifically to reply to that, my take would be:
Hogan was/is never going to be a #1 WR, so who cares how intelligent/non-intelligent he is, he's a specialist type player not one of the backbones of an offense. Watkins, Matthews and/or Jones are or will be #1's, that's what I am comparing.
Peterman is not the starting QB, nor will he be unless Tyrod has a serious meltdown this season, so at the moment, he is not in the conversation that pertains to how well this team does this season. Maybe he does fit into the paradigm shift OBD is going for, but in terms of this season, no.
And as far as Wood goes, I think to play OL positions a player has to be more cerebral by default, plus I guess I never really watch the OL interview videos, I tend to gravitate towards QB and skill positions.
And I guess if you're saying that these threads don't start with white players as the subject, well, teams in the NFL don't have very many white players at skill positions. If the Bills had traded away a white #1 WR with Sammy's skillset and drafted a white WR like Jones and traded for a white WR like Matthews, then maybe we could be comparing that situation and the thread would be about white guys...
