I've tabulated the votes in this thread. It appears the most frustrating players in SJ history were
Single season assist leader and NBA player Omar Cook
Zendon Hamilton, who averaged nearly a double double for his career and played half a dozen years in the NBA
NBA player Felipe Lopez, the third leading scorer in school history
McDonalds all american and cup of coffee NBA player James Scott, who averaged 12 pts/4 reb /2 ass in two years
BE sixth man of the year Justin Burrell
At first glance that might look the Saint John's Third All Century team. But when you have the storied history of winning that Saint John's does, those guys are the loosers.
