Around 3 p.m. weekdays, a man’s voice echoes through the halls of the new Seabury Academy building just outside the school’s new gym. Where tennis balls once bounced at the Alvamar Racquet Club, the shouts of the new Seahawk girls basketball coach ricochet off the rafters as he stresses rebounding of a different kind.

Meet Eric Nelson.

Along with the new gym, the high-intensity coach is looking for another addition to the Seahawk program.

“We got a new attitude, hopefully,” Nelson said. “We have high hopes for this year.”

Nelson joins the team after serving as a junior varsity coach the last two years for Seabury. He has been living in Lawrence for three years, after moving from Durango, Colo., where he coached everything from downhill skiing to tennis.

The new coach is optimistic despite having a relatively young squad; the Seahawks have no seniors, three juniors, four sophomores and five freshmen.

And then there’s the two JV teams brimming with players.

“We got a pretty good farm system,” Nelson said with a chuckle.

What Seabury has is youth. What it needs are wins. Nelson is going to need these relatively inexperienced players to step up to improve on last year’s 4-12 season during which the Seahawks fell shy of the 20-point barrier on several occasions.

The top source of points last year was Lindsey Ahlen, but Nelson insists that his team has to be balanced and not always rely on the sophomore for buckets.

Nelson has not yet figured out his starting lineup, but is hoping several Seahawks help anchor that balanced attack — namely juniors Laura Frizell and Linaya Newstrom, and sophomores Laura Hoffmann and Melinda Nichols.

Freshmen Erika Hierl and Jennifer Crawford also will see the court, Nelson said.

Being a small and young squad, the team will look to be a quick and feisty bunch, Nelson said. Seahawk fans can expect a lot of up-tempo, drive-the-ball-up-the-court play on offense. Defensively, Seabury will rely on a lot of presses.

“People will know they have been in a battle when they play us,” Nelson said. “That’s what I’m trying to instill.”

He’s also trying to coach a team in a new building by doing some building of his own: the start of a good basketball tradition.

“It’s gonna be exciting,” Nelson said. “We’re gonna pack the place. People who have not seen the transformation of the Alvamar Racquet Club should come and check out the facility. It’s a great place to watch basketball. It rivals any of the city gyms, I think.”

The Seahawks open their season Thursday at the Williamsburg Tournament.
