Devon Moore hears the jeers whenever the Delone Catholic High boys' basketball team travels.

"You're not as good as your sister." "You'll never be able to go to Duke."

Moore, of course, is the younger brother of former Squirettes star Sierra Moore, a Duke Univeristy freshman who earned a scholarship to play basketball. But his team-high 15.7 points per game don't stop opposing fans from reminding him of his sister.

"It's happened pretty much every away game," he said. "I don't let it bother me. I try to block it out and keep playing and keep shooting. It makes me want to shoot a 3 in somebody's face."

Not even his home gym offers a respite. Moore practices and plays underneath a banner honoring his sister being named the 2011-12 Gatorade Pennsylvania Girls' Basketball Player of the Year.

As the Squires open the YAIAA tournament with today's 8 p.m. game against Dallastown at Spring Grove High School, he hasn't let the image of his older sister impact him.

"It's nice being her little brother," he said. "But I like to think of me as my own person. I like being known as Devon Moore, not Sierra Moore's little brother."

His attempt to do so hasn't been easy. He missed his freshman season with a torn left ACL -- which he rehabbed from last spring with Sierra, who was training for track postseason -- and didn't return completely to playing shape until the summer.

"He's doing a terrific job coming back from that situation," Squires coach Jim Dooley said. "It's very difficult."

Moore, playing his first year of varsity basketball, is also learning the motion offense, which is similar to others in that the point guard brings the ball downcourt and starts the play, but different in that each player is expected to be in motion after that. There are no positions.

This requires each player to show versatility and be able to handle the rebounding duties of playing in the paint and to have the ballhandling skills of playing farther from the net.

"If you're going to develop as a player, motion is the best thing you can do," Dooley said. "You're just a basketball player looking at the man in front of you. He'll tell you what to do -- screen, roll off screens, read. It's an unending process of movement. The first rule is don't stand."

Moore believes this season has helped him develop his knowledge of what to do on the court.

"He said that?" Dooley said. "That puts a smile on my Irish face."

To help him this season, Moore has been able to use his years of 3-point contests with his father, Edwin, and one-on-one sessions with Sierra that stretched until 11:30 or midnight at times on their family halfcourt. He said she beat him until he was about age 13, but that he started winning as he grew taller.

"She couldn't handle me in the paint," he said.

Moore wants to play in college, just like Sierra and their father, who did so at Millersville from 1984-87. But he needs to keep improving to reach that level.

"There's a lot of things he has to improve on, just like any kid," Dooley said. "When you're talking about an athlete like that, it's a day-by-day progression. But for his overall development, you have to get better at everything. I think he has a great future."

As the end of practice approached Monday, Dooley challenged the Squires to make 40 3-point shots in three minutes from each side of the court. Before he attempted his first shot, Moore said it would be the first make but missed.

The shots soon started falling in as Devon Moore keeps trying to make a name for himself.
