Yes. I think the gap between Tua and Burrow/Herbert/Fromm is big enough to still make him the best bet. Sitting a year isn't such a bad thing. The key is how you project his recovery and longterm health, and when I say Tua >, I'm projecting a full recovery in 2021. If that's not the case, it obv changes things.
I'd be more inclined to pair Tua with another QB. Huntley makes sense to me, because he's shown enough to say he has a real chance, and he'll likely be the cheapest QB you can address that way. Quick feet, throws with touch and zip, accurate, efficient, protects the ball, and makes big plays. His big problem is that he sometimes freezes up and takes bad sacks - loses yards he shouldn't. His QB instincts have improved a lot but still need work, but his athletic instincts are outstanding, and he's proven to be a smart player. Different package, but I see similarities to Dak.
I really like the the Tua/Huntley pairing, though, because you're giving yourself two shots at high-ceiling QB's at a relatively minimal investment. Healthy Tua is just clearly so much better than any other QB in this class or next (at this point). Getting him anywhere but #1 is stealing (if he's expected to recover). Huntley is better than QB's recently drafted in the 1st and 2nd Round. He's projected Day 3 or UDFA. So, you're left with plenty of premium assets to build around them.
