I actually did a good breakdown on another site and looked at how Tua, Jackson, Allen, Mahomes, and I think one or two more QB’s did against like teams. For example, how did Allen do against KC compared to how did Tua do against KC.
What I found was, with the exception of Mahomes, all the other QB’s played very similar to each other against like teams. There’s not some glaring difference.
What I think most people’s problem is, they look at wins and losses and attribute them to one player out of 53. Josh Allen can have a 75 PR and the Bills will win so he gets credit for the win. Tua has never really had that luxury. He needs to play perfect, or the team loses. That’s not realistic.
