Arcerti did struggle against two of the best going 10 of 25 against TD Ierlan and 12 of 37 against Gallagher. He did finish with a decent .549 pct.
PSU did play a relatively good early schedule, also playing Villanova and Cornell, and not just cake like Georgetown.
In the end, basing selections on statistics from a 6 or 7 game season where the schedules were very uneven in strength is something only a narrow-minded person would do. Both Dox Aitken and Bubba Fairman were in shooting slumps last season, and their numbers were not great but they make the team. Arceri has been one of the top FO men for years.
