Kyrone Fox threw two touchdown passes and ran for won in the first half to lead visiting Dulaney (2-3) to a 36-0 victory over Catonsville (1-4).
Linebacker and lineman Chance Thames was stellar on both sides of the ball.
Jevonne Hawkins caught two touchdown passes, including one from reserve quarterback Brian Graziano.
It was the first shutout of the season for the defense.
"It was a good team win on defense each level, from up front to way back, we were there," Thames said. "It does feel good to finally get that winner."
The defense set up the first touchdown when Jeremiah Wynn intercepted a pass and lateraled to Hawkins and he advanced it to the one.
But, a penalty brought the ball back to the 20-yard line.
Three plays later, Fox scored on a 10-yard quarterback draw.
The extra-point conversion run attempt was stopped by Catonsville's leading tackler, Jorge Urizar, and the Lions lead was 6-0 with 9:25 left in the first quarter.
Catonsville, which lost its starting quarterback Javon Williams in the first half of the first game of the season to a broken arm, started Jaleel Brown as the signal-caller.
On the Comets next possession, Thames made three tackles, including getting Donnell Jones Jr. for a 6-yard loss.
Thames deflected the praise for his big plays.
"With the D-line in the trenches, they did their job by penetrating and it allowed me to play free," Thames said.
A 6-yard pass from Brown to Marciss Lawson gained six yards and a 9-yard scamper by Brown set up a fourth and one from the Dulaney 30.
But, the Lions stopped Brown on a quarterback sneak and the Comets turned the ball over on downs.
A botched handoff on Dulaney's next play led to a fumble that was recovered by Catonsville's Michael Bowers at the Dulaney 26.
On the next play, Jones was tackled by Thames for a 3-yard loss.
Two plays later, Brown ran eight yards to the 21, but a fourth and two from the 21 was incomplete and the Comets turned the ball over on downs again.
Catonsville's next possession resulted in an interception by Wynn that was returned 39 yards to the Comets 25.
Fox connected with Lane for a 23-yard completion, but he fumbled the next snap on the 2-yard line and Urizar recovered for the Comets at the one.
Still, only trailing 6-0 early in the second quarter, the Comets got out of the poor field position when reserve quarterback Kris McIntee connected on a 15-yard pass play to Jakob Saak.
But, Jack Reilly tackled Brown for a three-yard loss and two incompletions forced the Comets to punt.
"That's one of our goals, to win sudden changes, not let them score when something goes wrong," Thames said. "The offense has got to drive and the defense has to hold them, so it's a team effort."
The offense did get it in gear in the final 5:37 of the first half.
Fox threw all the way across the field to Hawkins for a 28-yard touchdown and a conversion run by Geronimo Woodard made it 14-0.
After a blocked punt, the Lions took over at the 35.
Hawkins scored from five yards out on a sweep, but the touchdown was nullified by a holding penalty that moved the ball back to the 16.
Fox hit Lane on a slant for a touchdown on the next play and Lyde's run for the conversion made it 22-0 at the half.
Thames was impressed with the play of his starting quarterback, but even more excited about the whole passing game.
"It's building up, it's getting confidence and it's a credit to the line for keeping him upright, so he can throw the ball downfield and find those guys and credit to the receivers who are not giving up, whether they are open or not, for keeping their routes, so it's everybody doing their part," Thames said. "It's like the perfect storm and the guys just came together."
Fox left the game with a shoulder injury, but the Lions offense didn't miss a beat because they played together.
"We are all about family," Dulaney coach Daron Reid said. "It was a good team win."
