It’s interesting that you bring up Mahomes. I’d suggest that they’ve gone through a similar evolution. Tyreek Hill (like Diggs) is gone. Their coaches obviously felt Mahomes could drag a new WR room over the top, and by their successes it seems like he has. You have to admit, they’ve done it without a room full of superstars. In the longer perspective, the Bills have been chasing pass catching TEs. So much so that they felt they needed two. I opine that it goes back to the punishment that they endured from that position back to /Hernandez and now more recently with Kelce.
