We don't know what will be available at 20. There are always surprise risers and fallers.
That said, I would not take QB at 20 unless there was a surprise drop. Lance is raw and has not played elite competition.
Jones is accurate but not mobile, which probably makes him a better Nick Foles, IMO. For comparison, Tua graded higher. He might get replaced in Miami.
I do think we should draft a QB, it is a deep draft. I personally like Kellen Mond as a draft and develop. But not round 1.
I also dislike the Moore pick. A 1st round WR should be your #1 and in most cases, your #1 should be a bigger, high-point WR like A-Rob.
This draft is deep in OL. Christian Darrisaw, Rashawn Slater, etc. There are half a dozen that would be worth our pick. Grade them out and take the highest grade available.
