I wonder if the run on DTs last year is affecting the demand this year.
I ran 12-15 mocks this week using the NFL Mock Draft Database Simulator, which runs off of the Consensus Big Board, which is what the writers at ACME Packing Company use.
FWIW, Christen Miller was almost always available at #52. I think once he wasn't. Dani Dennis-Sutton was rarely available at #52; he frequently was picked by the Lions at #50. And that makes a lot of sense - I know they really want to have at least somewhat of a threat opposite Hutchinson, so I would not be surprised if the Lions go Edge at #50. Orange was always available at #52; they have him at #70 overall.
Right now all four of McDonald, Miller, Hunter, and Orange are still available.
