I’d add dischinger, JBC, and scheelhase to that list.
Number of 30 point games in career:
Mount - 46
Scheelhase - 33
Dischinger - 30
Robinson - 25
JBC - 10
Edwards - 9
Number of 30 point games in season:
Mount - 22 (1969)
Robinson - 18 (1994)
Scheelhase - 14 (1966)
Dischinger - 14 (1962)
Mount - 13 (1970)
Scheelhase - 12 (1965)
Mount - 11 (1968)
Dischinger - 9 (1961)
Robinson - 7 (1993)
Scheelhase - 7 (1964)
Dischinger - 7 (1960)
Edwards - 7 (2019)
Edwards’ 2019 ranks as the 11th highest single season scoring average in school history.
It would be easier to rephrase your original statement of “he’s the most prolific scorer in school history” than try to mine data that somehow supports your opinion.
So, if you were starting a team tomorrow, who would you pick first off that list?
