Sheldon was a 4th rounder. Not a major toss of dice. Boom or bust. Carman was a bad pick in that he was a natural LT and they not only used him too early, they put him at a position he had no business (or experience) playing. Both, however, were above average at the collegiate level.
A flub-up on a night out on the town does not discount what he did on the field at Texas. There may be better “value” picks at NT later on, but for a true description of what the Bengals need as a pure NT, he is it.
The Bengals met with him…he’s been vetted. If they suspected a chronic issue, then that is one matter.
