I've tried to think of how many coaches have been fired after 2 years and I have trouble finding many. It looks like 3 is the magic number.
Tracy Claeys (Minnesota) - 2 yrs
Darrel Hazel (Purdue) - 4 yrs
Ed Oregon (Ole Miss) - 3 yrs
Sonny Dykes (Cal) - 4 yrs
Tony Levine (Houston) - 3 yrs
Skip Holtz (USF) - 3 yrs
Bob Diaco (Uconn) - 3 yrs
Ron Prince (KStste) - 3 yrs
Paul Wulff (WSU) - 4 yrs
