The way I read it he's currently tied with Leahy, Holtz, and Ara, but will be 2nd all time in seasons coached this fall
In 11 years, he's had ND playing for the NC 3 times, either a title game or playoffs, and in position in December 2-3 times more. The state of the program when he took over was abysmal. Not just the records of the previous 3 regimes, but also the:
Facilities - Not only were these only not-elite, but not even mid-Power 5 level
Support structures - Players were losing weight over the season due to inadequate nutrition, now ND has Combine Freaks
Fan atmosphere - Down-in-front, golf-clap millionaires are still there, but the overall energy is much better
NFL pipeline - we're putting top 3 rounders into the draft pretty much every year now, with a handful of Pro Bowlers/All-Pros
Rooms for growth:
Elite skill recruits
Elite wins every year - Clemson this year regrettably gets an asterisk after they pants us in the ACC Championship... I still think Trevor wouldn't have done more than the backup but we'll never know
My hot take/troll - If he wins even just one title, he's a Top-3 all time HC at ND, behind Rockne and Leahy, based on where he took ND from
