I think he could eventually be a decent 3 point shooter. I'd be curious to see how well he shoots in practice.
If none of the bigs can shoot the 3 that means it will get harder and harder to score as the season goes along and teams start cheating on defense (which has already started happening)
Need at least one of the bigs to be a reliable 3 point shooter this season. Maybe that will be Fouss, maybe not.
