I think it is harder for Notre Dame to win now than it was in 1988. Back the, ND had a lot of built-in advantages --- mostly stemming from tradition, name recognition, and television exposure.
But, the 85 scholarship rule along with the explosion of nationally-televised games and media coverage has diluted a lot of those advantages.
The 85 scholarship rule has spread talent to more programs that are historically second-tier (i.e. Stanford, TCU, Baylor). Back in '88 Notre Dame could tout playing on national television a lot, but today most FBS teams play on national television regularly and even weak P5 programs play nationally-televised games almost every week.
ND used to be a media market unto itself, but now most regular top=25 programs are awash in similar exposure.
ND can still sell itself as a great university and a tradition-rich football program. But, those things might not mean as much to today's recruits as the sparkle and flash available at at least a dozen other programs.
