McLaughlin has played a key role in all three victories.
"I'm just playing with a lot more confidence," said the 6-foot-5 McLaughlin, who lives in Mt. Laurel. "My shots are falling, and when they aren't, I keep attacking."
Senior guards Austin Wetzler (16 points) and Phil Cunha (15) combined to make eight three-pointers, and junior guard Jake Silpe added 10 points with six assists for No. 5 Cherry Hill East (15-3), which lost its second in a row.
"That's a good team," Cherry Hill East coach Dave Allen said of Eustace. "They have all the pieces, and they're playing very well right now.
"We've hit a little tough stretch. We've come up short two games in a row."
In a game played before two enthusiastic student sections, Bishop Eustace won most of the battles on the backboards and for loose balls. The Crusaders also ran the floor, with DaSilva and McLaughlin leading the way.
"It's finally clicking," DaSilva said. "We're playing with the energy we need to play with."
Bishop Eustace coach Bob Falconiero said his team can beat any team on its schedule.
"We can lose to anybody, too," he said.
The Crusaders' recent surge has coincided with McLaughlin's improved play. The junior saw major minutes as a sophomore and was a steady contributor earlier this season.
But he has taken his game to another level in the last couple of weeks.
"Conor is a good player," Falconiero said. "He's starting to believe he can do it. He is just starting to get to his growth as a player."
