He is not a franchise QB. If teams had to redraft from the current pool of QB's, how many would be taken before Tua? Allen, Mahomes, Burrow, Herbert, Stroud, Prescott, Jackson? Probably even Hurts, Love, Lawrence, and Purdy? Plus you have some old guys who are better than him like Rogers and Stafford. So, I don't belive he can be categorized as a franchise QB. He is a decent QB, but not a franchise QB.
PFF ranked him 14th!
