The available choices for this century are:
Didn't/Barely played at NU
Gary Lee (MD Eastern Shore), Chier Ajou (Seton Hall), Johnnie Vasser (Tennessee Tech),
Rapolas Ivanauskas (Colgate, Cincinnati)
One or two seasons at NU
Kyle Rowley (St. Mary's), Kale Abrahamson (Drake, Duquesne), Isiah Brown (Grand Canyon, Weber St.), Jared Jones (Middle Tenn., San Diego St.), Casey Simmons (Yale), and Julian Roper (ND)
Three or more at NU
Aaron Falzon (Quinnipiac), Jordan Ash (Wright St.), Barret Benson (S. Illinois), Anthony Gaines (Siena), Pete Nance (UNC), Miller Kopp (IU), Robbie Beran (Va. Tech), and Ryan Young (Duke)
I guess you could make an argument for Ryan Young, though he was surrounded by a ton of talent. Jared Jones became a pretty decent player in his 3rd year at Middle Tennessee and is now in his 6th year of college at San Diego St. Kopp's final year worked out well for him once he was the 5th option on the court instead of the top. Isiah Brown improved a lot by the time he got to Weber St. Rap had one good season at Colgate but couldn't replicate it the following year.
So yeah, not sure there's a real great answer.
