Also from your source (NCAA):
The repeat-violator legislation (?death penalty?) is applicable to an institution if, within a five-year period, the following conditions exist:
1. Following the announcement of a major case, a major violation occurs and
2. The second violation occurred within five years of the starting date of the penalty assessed in the first case. The second major case does not have to be in the same sport as the previous case to affect the second sport.
On point 2, UNM has been assessed penalties against their WBB & track teams...both within 5 years.
