Most of Thompson's work was done in the first half, when he ran for 196 of those 220 yards. But he wasn't needed in the second.
And that was thanks to an opportunistic Titan defense, giving up plenty of yards but capitalizing on mistakes.
Carl Albert intercepted four passes, three coming in the second half.
Thompson, who plays both ways, picked one off in the third quarter.
Then, defensive backs Bryan Williams and Dillon Lohr each took an interception back for a touchdown in the fourth quarter, turning a comfortable lead into a blowout.
“Our defense kept them down from making big plays,” Rose said. “And we made big plays ourselves.”
Next week, Carl Albert will meet Bishop McGuinness in the semifinals, a team that beat the Titans 42-32 earlier this season.
“They beat the crap out of us,” Rose said. “We weren't a very good football then. I think we are better. And we're looking forward to it.”
