Which 1st Rounder will beat expectations and which will fall short

I think that it's going to be a rough season for rookies.
No offseason workouts. No rookie minicamps.
Remains to be seen how training camp and regular season shapes up in the coronavirus era.

That highly favors the gym rats and workaholics like Burrow. If they can't outplay you, they will outwork you. Burrow will round up a playbook and few WR's, go to a gym somewhere, and get their timing down.
