Seattle made the most 3s last year, with Bird, Loyd, and Stewart (in that order) topping the team in made 3s.
Chicago had the highest 3-pt% but were only 6th in made 3s.
PG (Vandersloot & Faulkner) and Center ( Dolson & Coates) are pretty well set for Chicago, so their needs are at 2-3-4. I could definitely see them grabbing Williams and a more offense-minded wing with the 3rd and 4th picks.
