Leilani Mayer didn’t know much about the Northwest volleyball team when she transferred to the Germantown school, only that it went to states the previous year.

“I was like, okay, so they have to be good in some sort of sense,” she said.

Exactly how good the Jaguars were this season was a shock not only to the 6-foot junior from California, but also to her coaches and teammates. Northwest (20-0) went undefeated en route to a Maryland 4A state title, its first in school history, and the top spot in the final Post volleyball rankings.

The Jaguars were a title contender well before they stepped foot inside Ritchie Coliseum at the University of Maryland. The 2014 state finalists brought everybody back, and then some, including a deep senior class, two impact freshmen (Jenaisya Moore, Rachael Bennett) and the talented transfer from Bishop O’Dowd.

“I knew that we were gonna be really good, but I knew that there were going to be challenges and one of the biggest challenges was that we were so good,” said Coach Stephanie Blake, whose sister, Tara Smith, was an assistant. “They always just dug down really deep.”

The Jaguars overcame the few obstacles that were in their way. In a regular season match, they trailed Gaithersburg by two sets before completing the comeback victory. Against Sherwood, they dropped the first set and then won in four. In the state semifinals, they avenged last year’s final loss by defeating defending champion No. 5 Severna Park in four sets.

Though some matches were tough, Mayer said the hardest competition was themselves. Playing against each other in practices helped prepare the Jaguars for the tough Montgomery County schedule and the rigors of the postseason.

“I feel like I play against the best. My teammates are some of the best people I ever played against,” Mayer said. “When we get to the hard teams, it’s like, this is just like practice.”

Mayer will be practicing with a new set of teammates next season. The Jaguars have nine seniors, including outside hitters Gabby Bennett, Emma Liller, serving specialist Chaya Riggs, and middle hitter Biamba Tshitenge. But the state championship expectations remain the same, Mayer said.

“That crossed my mind the moment I stepped on the court. My team is half seniors,” Mayer said. “It’s training time right now.”
