I put in the top ten teams faced for some context of how many difficult opponents they faced.

Just missing the cut at nine games were Pat Dye (.722), Tommy Tubs (.667) and Houston Nutt (.444)

Some other notable bowl records:

Bob Neyland (2-5)
Gus Malzahn (2-5)
Gene Stallings (5-1)
Urban Meyer (5-1)
Ed O. (4-1)
Wally Butts (5-2-1)
Doug Dickey (2-7)

A minimum bowl games played must be applied.

If we took it down to 3 minimum, here's the top of the list:

Jim Donnan 4-0
Gene Chizik 3-0 (Did win it all in one of those)
Jimbo Fisher 3-0 (Guess opt outs don't count against you)
Brian Kelly 3-0 (Suck it Notre Dame)
Butch Jones 3-0 (Champs of Life can't be defeated)
Sam Pittman 3-0 (Somebody buy that man a ko beer)
Ray Perkins 3-0 (Better than the Bear and Nick combined)
Gerry DInardo 3-0 (Now Kelly's perfection seems less impressive)
