Kaden Jones took the opening kickoff to the house and Casmen Jones added a 20-yard touchdown run two minutes later, ending any doubts about the outcome of the game in just 127 seconds of clock time.
By the time the game was over, it was 48-7 and the Lions had their fourth straight win.
The Lions went ahead 21-0 later in the first quarter on a 63-yard Jones touchdown before Kellyville got on the scoreboard.
After that, Jones hit fellow senior Jarin Greenfield with 10-yard touchdown pass, ran nine yards for another and through to Brayden Nation for a touchdown to make it 42-7 at the half.
The Lions closed out the scoring when Jones had Alec Jackson for an 89-yard touchdown with about 4:00 left in the third quarter.
The Lions move on to the regular season finale Friday night at Prague with a district title at stake.
