Well, at #6 -
Top two QB's are certainly gone (Lawrence and Wilson)
So, I think the only two that have a case there are Fields and Trey Lance. I don't think they want the drama around another North Dakota QB this year (even if its the right pick as they are different players, I think it creates a whole mess of comparisons and expectations we dont want)
So - it would be Fields vs Chase/Smith vs Surtain most likely.
I would probably not go QB, and instead sign a vet to compete with Hurts. This team isnt going to be able to support a rookie QB, and getting a top offensive talent at 6 to put in place first seems ideal. You get a year of development, a year to evaluate Hurts, a year to see if your Oline can stabilize - and next year, you are in a MUCH better cap position, and can sign some talent to put around a rookie QB next year (if Hurts doesnt look the part).
