I didn't vote for anyone in the dark ages of college football, so guys like Knute Rockne (.881 pct, 3 NC's), Fielding Yost (.832 pct, 3 NC's), Walter Camp, and Pop Warner didn't make the cut.
1. Frank Leahy, Notre Dame (1941-1953), 87-11-9 (.855), 5 NC's (1943, 1946, 1947, 1949, 1953); Leahy's five NC's in 13 years is truly an amazing achievement.
2. Bear Bryant, Alabama (1958-1982), 232-46-9 (.824), 4 NC's (1961, 1965, 1978, 1979); Bryant reigned in the SEC before the rise of southern football (especially Big Three football), but he still put together a stellar record.
3. Barry Switzer, Oklahoma (1973-1988), 157-29-4 (.837), 3 NC's (1974, 1975, 1985); slightly over Bud Wilkinson (145-29-4, 2 NC's) because Switzer faced tougher competition in the Big 8.
4. Tom Osborne, Nebraska (1973-1997), 255-29-3 (.836), 3 NC's (1994, 1995, 1997); known as a choke artist until he won 3 NC's in 4 years at the end of his career.
5. Woody Hayes, Ohio State (1951-1978), 205-61-10 (.761), 3 NC's (1954, 1957, 1968); somewhat of a homer pick; Woody would have been at the top of the list if he could've "closed" a couple of times between 1969 and 1975.
HM. Ara Parseghian, Notre Dame (1964-1974), 95-17-4 (.836), 2 NC's (1966, 1973). Notre Dame football would have been a joke a couple of decades earlier if it hadn't been for Ara. In the ten years between Leahy and Parsehian, the Irish went 51-48-0 (.515) with no NC; Ara's worst season in South Bend was 8-3-0 (.727), and he brought ND back to the top of the CFB world.
