You can be proud of what you accomplished and also want to get better; it's not an either/or thing.
Also, you have to have realistic goals. On some level, you aren't happy with anything but a championship. But on another level, you have to recognize that having two consecutive tournament quality teams in years 4 and 5 and winning a game in the tournament is about as good as anyone realistically would have hoped for when Pikiell started. It doesn't mean we can't demand more eventually, but being dissatisfied now is ridiculous.
