Yeah, having a senior PJ Hall and a senior JG3 is a good start to a top-20 team. Their top-4 guys in PER (Hall, Schieffelin, JG3, and Godfrey) are 1, 5, 2, and 6 on the team in FGAs. The two others in the top-6 in FGA (Wiggins and Hunter) are their top 3-point shooters other than Joe and Hall. And they're not slouches. For comparison, On Syracuse the top-5 in FGAs (and their respective team rank in PER) are, in order: Judah (4), Starling(6), Bell(7), Taylor (9), and Copeland (5).
Too many shots taken by guys who aren't scoring leads to poor efficiency.
Also, Syracuse's leaders in FGA have disappeared in admittedly limited conference play. PER isn't the end all be all, but it's a good barometer of offensive contributions.
Player (Season PER) (Conference PER)
Mintz (22.2) (10.8)
Starling (10.6) (10.8)
Bell (10.1) (-3.1)
Taylor (9.0) (1.8)
Copeland (20.1) (25.1)
Brown (26) (31.6)
Brown should be leading the team in FGA.
