Roskopf quickly carved up Notre Dame's defense, finding open receivers all over the field. He threw two touchdown passes to Jhaheem Brown and two to Zerek Sidney, including a 61-yarder that gave the top-ranked Scorpions (3-0) a 40-7 lead with five minutes left in the third quarter.
Roskopf, a Washington commit, has quietly thrown 12 touchdown passes in Desert Edge's first three games.
But the story of its season so far has been the defense, led by electric junior edge rusher Jalanie George, who had another monster game.
When Notre Dame's Austin Bush ran 3 yards for a score with 7:21 left in the second quarter, it was the first time this season that Desert Edge allowed a touchdown. The score came after Desert Edge twice lined up offsides on two Notre Dame field-goal tries. With short yardage, the Saints picked up first downs both times, leading to the score and a 7-6 lead.
"I feel like we got cheated, but at the end of the day, we shot ourselves in the foot," George said. "Nobody is really better than our defense. "
Desert Edge then ran off 40 straight points, sparked by Roskopf spreading the ball to several receivers.
Aiden Honeywood hauled in a 32-yard scoring pass that gave the Scorpions the lead for good.
On the next series, Roskopf hit Brown for a 5-yard score.
"They make it easy for me, make good stops, and put us in good field position," Roskopf said about the defense. "I try to see the whole field and get it to the right guy. They're all playmakers and great players. "
Coach Henri MacArthur was happy with how the team responded after Notre Dame punched in the first points allowed by the Scorpions' defense.
"We're playing really well to start out," MacArthur said. "I'm disappointed we gave up that touchdown. It was the first points we gave up in three weeks. It was self-inflicted. But I'm proud of our effort on defense through three weeks. Playing great defense is part of who we are. "
