In its bid to conquer a third straight undefeated opponent, West Catholic's defense needs to switch gears.

In the PIAA Class AA state quarterfinals and semifinals, the Burrs ousted a pair of run-oriented foes. Next up, in a championship game noon Saturday at HersheyPark Stadium, is pass-happy South Fayette.

Lions quarterback Christian Brumbaugh, a 6-foot-4, 200-pound senior ticketed for William and Mary, has completed 226 of 339 passes for 3,615 yards and 50 touchdowns, with eight interceptions.

South Fayette, the District 7 champion, is located in McDonald, about 20 miles southwest of Pittsburgh.

Here is a closer look at the game:

Coaches. South Fayette's Joe Rossi owns a 61-33 record (.649 winning percentage) in nine seasons. Before taking over the Lions, he coached at District 7's Riverview, a Class A school. In 12 seasons with the Burrs, Brian Fluck is 108-49 (.688).

TV. The game will be televised live on the Pennsylvania Cable Network.

Quick facts. In the Class AA state basketball final last March, South Fayette nipped Strawberry Mansion, 49-47. After dropping two of its first three football games, West has won 11 straight by a combined score of 450-94.

Mad bomber. For his career, Brumbaugh has thrown for 7,052 yards, a Western Pennsylvania Interscholastic Athletic League record, and 86 TDs. Last week, in a 49-12 romp over Forest Hills, he was 21 of 31 for 362 yards and six TDs.

Quality slasher. West's Brandon Hollomon, a 5-11, 155-pound senior tailback, has carried 127 times for 1,444 yards and 17 TDs. With 3,151 career yards, he is 8 yards shy of his brother Rob's school mark.

Spread attack. The Lions' pro-style offense is also spurred by 5-11, 175-pound senior halfback Jeff Davis, who has carried 197 times for 1,555 yards and 15 TDs. Fullback Trevor Fiorentini, a 5-10, 210-pound junior, has rushed 30 times for 265 yards and six scores.

Stifling unit. West's defense, yielding 9.8 points per game, is led by end Jim Lynch (82 tackles), inside linebackers Kevin Burns (97) and T.J. Waters (69), and outside linebacker Anthony McDonnaugh (57).

Receiving threats. Brumbaugh's top targets are Tyler Challingsworth (71 catches for 1,047 yards, nine TDs), Davis (48 for 738, 10), Josh Patterson (37 for 601, 13), and Zach Hollingsworth (36 for 792, 11).

Special teams. On kick returns, Davis and Tyler Challingsworth are both averaging 27.8 yards. Tyler Lee has booted three field goals and hit 75 of 82 extra-point attempts.

Analysis. Fluck is right. Brumbaugh, able to connect on passes all over the field, has the arm to expose a secondary's weaknesses. West, though, has the speed and athleticism to counter a full-fledged aerial assault. With 205 yards and four scores from Hollomon, the Burrs win a wild one.

Pick: West, 35-31.
