Of course it hurts to see teams we care about lose. I was disappointed in how the hockey season ended. That doesn't diminish the accomplishment of reaching the Frozen Four. Lacrosse has come agonizingly close to a national title in recent years.
To borrow from Taxman, postseason success depends on getting enough at bats. If a team is in the NCAA tournament on a regular basis, they have a chance for a breakthrough performance. Aside from football and baseball, most ND sports are competitive. I feel lacrosse, soccer, or hockey will have opportunities to win titles in the future.
