I'll go under because with Parsons, Armstrong, and Fowler in the rotation at RDE I just don't know he gets enough snaps to realistically do it. He played 27% of the snaps last year and averaged a sack every 68 snaps which is about 1 a game. If he matched that sack rate and saw an increase in snap count to 50% that should equate to 8.5.
I'm excited about Williams this year based on what he flashed last year, but we also have some other rotational components that also deserve playing time. A Sam Williams playing 40-50% of the snaps with Armstrong and Fowler each taking the other 30% may yield more sacks than Williams playing 75% of snaps.
