With all due respect the problem goes higher than Sawrbrick, although he does figure in the equation.
With any great organization "winning" or being "great" starts at the top with that type of commitment whether it's a corporation, government, school, sports team (Pro, college, high school).
Notre Dame's administration does not have that commitment and it shows.
Notre Dame's last National Championship was in 1989 and the closest they have come to another national championship was a 2013 blow out from Alabama (42 to 14 with the score being 35 to 0 at one point).
As I have told many others, it's time to embrace the program for what it "is", not what it "was".
If fans want a 10-2 or 11- 1 season then start scheduling Harvard, Yale, Princeton, etc...although that's no guarantee either.
Notre Dame will never again even sniff a national championship let alone win one.
Embrace what it is and get used to it.
