Some interesting nuggets I just noticed:
At 92 wins, if Kelly were to coach a perfect season next year and win a National Championship he would eclipse Rockne's number of wins at Notre Dame with 106. He's already coached more games than Rockne as of this season at 129 (Rockne had 122 with 105 wins-12 losses-5 ties). If Kelly stays on for the 2021 season he will almost certainly eclipse Rockne's total wins baring a disastrous season.
Other notables:
Lou went 100-30-2 in 132 games at ND. Lou coached the most games for ND. BK could very well eclipse both Lou's wins and obviously Lou's total games coached next season, but will still be about 5% worse in winning percentage.
Ara went 95-17-4 in 116 games at ND. BK has already coached more games than Ara as of this last season, but he has 3 less wins and twice as many losses.
Leahy went 87-11-9 in 107 games at ND.
It should be noted that while Kelly is eclipsing some totals here, 2020 will be his 11th season as ND's coach. Leahy, Ara, and Lou all coached 11 seasons in South Bend and arrived at their totals playing less games per season. Rockne coached the most seasons at 13.
