"They're a good team than can win their league," Notre Dame coach Mike Brey said. "We lost to a good team."

"I think our second-half start hurt us," Brey said. "They get really confident. Their transition is so effective."
Monmouth (3-1) also got 15 points from Micah Seaborn.
"I'm very excited that our kids believed in each other, that they felt like they belonged on the court," Monmouth coach King Rice said. "When you believe in each other, anything can happen."
