In the last 4 years, ND lost LH in 2/10, Abro in 12/11, and (effectively) lost SM* in 1/13. IIRC, it earned 2 7 seeds and 1 6 seed in those 3 seasons. In the 1 season where ND didn't lose a key player, it earned a 2 seed.
For a program that started each season w/ a visible talent deficit compared to elite BE programs, posting that record while losing such talent is remarkable. I'm not sure that Pitino would've done much better under the circumstances. I seriously doubt that Boeheim, Williams, Calhoun, or JT III would've done any better, and some of them probably would've done worse.
Obviously, March is another story. That horse was beaten pretty well here in recent weeks, and I have little meaningful to add that I haven't said already. I will merely reiterate that there is a visible difference between MB's 1st 3 NCAA appearances and his last 6 appearances. I will, furthermore, note that the 3 former teams had visibly better top-line talent than the latter 6 teams.
Looking ahead, I have no clue as to what it portends w/ the incoming talent upgrade. Barring serious injuries, if ND continues to be unable to beat anything better than a 12 seed in the next 2-3 years, the program needs to head in a new direction. In the meantime, however, watching Syr and UL in this year's NCAAs led to some thinking about ND's performance in recent years.
*SM was a valuable contributor in first 2 games, both of which were solid wins. He was a non-contributor thereafter.
