They, or the author Ben Muth, are not optimistic. Kind of what people have said; powerful guy to shove defenders on runs but too slow and awkward on pass protection. They think he will get destroyed by good, edge pass rushers. Like Von Miller.
It was raised in the questions whether he could eventually move to guard, to offset that weakness. So perhaps over-drafted, but most likely will be an upgrade over Clary and maybe a long-term, strong guard. I see re-building our line as taking another 1-2 seasons.
