"I was kind of in a slump recently, I guess this was a bounce-back game for me," said Yoon, a senior forward who also had six rebounds. "I think our team just played good overall, which I think allowed me to play good.
"This was really important for us. I think just losing [those first two league games] made us rethink, 'How good are we?'"
The Falcons opened with a 49-36 loss to Burroughs before dropping a heartbreaking 34-32 loss to Burbank on Friday.
Hoover (1-9, 0-3), on the other hand, found a similar fate in its third consecutive lopsided loss.
"Three league games, three mercy rules," said first-year Hoover Coach Stan Watson of his team falling behind by 40 points and drawing a running clock. "That's just because we're not competitive."
The Tornadoes, who have lost six games in a row, have now dropped their first three league contests by an average margin of 47 points.
"We've been saying, really the entire season, it's not about other teams, it's really about us," said Watson of his team's philosophy of concentrating on its progress. "That's been our thing all year, focusing on ourselves, playing under control and doing the things we're taught."
But, from the onset, that failed to happen, as Crescenta Valley caused turnover after turnover on defense and shot 18 for 37 (49%) from the field to build an insurmountable lead.
Hoover's biggest highlight came from junior point guard Kariz Alberto, who scored a team-high 12 points, including all four of the Tornadoes' first-quarter points and six in the final period.
Crescenta Valley also got double-digit contributions from freshman forward Ella Stepanian (14 points) and junior point guard Catherine Davis (12 points).
Going forward, Watson remains patient and optimistic.
"We're trying to change a culture here, we just want to be more competitive," Watson said. "I'm gonna keep encouraging them.
"We'll keep climbing that mountain."
As for Perez, while he admits it's difficult for a team to keep its intensity up throughout a blowout, he said the second-half effort was lacking and example enough that there's still plenty of room to improve for his Falcons.
"We're not doing all the little things, which is our weakness," he said. "There's a lot of issues where we still need to learn basketball."
