Equating Harbaugh with Frost might be the most simpleminded comment ever on this board. Harbaugh is 64-24 at Michigan, has gone to a bowl every year but the Covid year, finished first in the Big 10 East twice, winning the Conference outright once, made a BCS final 4, and has current team ranked no 4 in the ESPN power rankings.
Frost was 16-31, never went to a bowl or had a winning season, never even finished higher than 5th in the weak Big Ten West, and left current team ranked 76th in ESPN Power rankings, right behind mighty James Madison.
Harbaugh also out-recruited Frost every year and was 2 and 0 against Frost at Nebraska, including a 56-10 spanking.
