For Rosemount, putting 2014 in the past is largely the result of facing 2015 head on.
The way last season ended was more than the typical end-of-the-year disappointment. With a senior-dominated roster and a top-flight passer in quarterback Jackson Erdmann, the Irish were the most dominant team in Class 6A. They won their first 10 games, with just one decided by fewer than 21 points. A Prep Bowl appearance seemed like a sure thing.
But in the state tournament quarterfinals, Erdmann suffered a broken leg early in the game. Lakeville North rallied in the fourth quarter to pull out a 14-13 victory.
"The whole team was crushed," senior linebacker Dan Monson said. "We didn't see that coming. It was devastating."
But that's history now. Dwelling on the past serves no purpose.
