No hockey team has crisscrossed the D.M.V. quite like O’Connell this winter. As members of the Mid-Atlantic Prep Hockey League, Washington Catholic Athletic Conference and Northern Virginia Scholastic Hockey League, the Knights have seen a wider variety of the area’s high school hockey teams and their rinks than any of their peers.

Last Wednesday, O’Connell handed No. 1 Gonzaga its first local loss of the season with a 4-3 shootout win in a WCAC semifinal. On Thursday in the WCAC final and then on Tuesday in a MAPHL quarterfinal, O’Connell lost to No. 5 DeMatha. Still, the Knights will challenge unbeaten Broad Run and Briar Woods in next week’s NVSHL playoffs.

“We’ve had the ups and the downs, but that has benefited us. We’re prepared to lose a game and then bounce right back up for the next league or the next competition,” said Coach Flip Collins, who has 13 freshmen and sophomores on his 20-player roster. “Some teams go one game at a time, but we sort of go one week at a time. We can live and die today and then just wake up and see who we play tomorrow.”

With its win on Tuesday, DeMatha advances to a MAPHL semifinal against No. 2 Landon, who tied the Stags 2-2 back on Jan. 17. In the other semifinal, defending champion Gonzaga will face Spalding.

In the Maryland Student Hockey League, defending champion Churchill and Blair, which handed Churchill its only league loss last month, are the last locals standings after Tuesday’s quarterfinals.
