In the Catholic and Public Leagues, it's championship time at the Class AAAA and AAA levels.

Here is a closer look at the four games:

Catholic League

Class AAAA final: Roman Catholic (7-3) vs. La Salle (9-1), at Northeast, 7 p.m. Friday.

Last meeting. Behind Jamal Abdur-Rahman's three touchdowns, the Explorers blitzed the Mike Keir-less Cahillites, 43-17, in Week 5.

Keir under center. Keir, a strong-armed sophomore who missed most of the first meeting because of a bruised kneecap, has thrown for 1,000-plus yards and 11 scores.

La Salle's QB? Who will be La Salle's signal-caller? Kevin Forster, usually a wideout, has filled in the last three games for Matt Magarity (concussion).

Said Explorers coach Drew Gordon: "We're not sure yet. [Magarity] has been out two weeks doing nothing. We're trying to see if he has his timing and energy back."

Pick: Roman's defense too often has been burned by big plays. If anyone can expose that weakness, it's Abdur-Rahman. La Salle wins its third straight crown, 31-14.

Class AAA final: Cardinal O'Hara (9-1) vs. Archbishop Wood (10-0), at Plymouth Whitemarsh, 7 p.m. Saturday.

Last meeting. With Desmon and Brandon Peoples combining for 331 rushing yards and five scores, the Vikings downed the host Lions, 48-34, in Week 9.

Quotable. O'Hara boss Danny Algeo, whose defense yielded 345 rushing yards in Round 1: "We need to play better up front, tackle better. They're going to make big plays. We have to limit the number of big plays."

Expected back. Archbishop Wood wideout and linebacker Sam McCain is expected to play after experiencing neck/head issues Saturday vs. Monsignor Bonner.

Injury update. Unlike two weeks ago, fullback-linebacker Brendan McLaughlin (sprained ankle) will play for O'Hara. Algeo said two-way back Damiere Shaw (concussion) is "questionable" and might sit out for a fourth straight game.

Pick: O'Hara will muster a better defensive showing, but it won't be enough to derail the ever-explosive Vikings. Wood, 27-21.

Public League

Saturday at Northeast.

Class AAA final: Roxborough (7-3) vs. Dobbins (9-1), 1 p.m.

Last meeting. Spurred by Terrance Stafford's 120-yard rushing effort, the Mustangs topped the Indians, 15-6, in Week 5.

Bruising back. Stafford, a 6-foot, 210-pound halfback, has gained more than 1,000 yards and 19 TDs. Rushing support comes from fullback Aaron Walker and halfback Daquan Brown.

Counter punch. Roxborough's catalysts are 5-6, 140-pound wingback Dre'von Williams and fullback Tymere Blue. Nick Butts has passed for 700 yards and 12 scores.

Quick fact. Dobbins, under fifth-year coach Lou Zambino, is trying for its second Class AAA league title in three years.

Pick: Stafford has been running wild. Roxborough's defense, like others before it, doesn't have the answer for him. Dobbins, 32-6.

Class AAAA final: George Washington (7-2) vs. Northeast (7-2), 4 p.m.

Last meeting. Like last season, the Vikings defeated the Eagles in the regular season. In Week 8, Northeast triumphed, 13-6, to clinch the Gold Division crown.

Back in the fold. Junior tailback Hakeem Sillman, unavailable in the first go-round, has returned to Washington's lineup.

Double threat. Northeast's Deion Barnes, a standout senior defensive end and top-flight Division I recruit, caught a 20-yard TD pass against Washington. He posted 11/2 sacks.

Quick fact. The Eagles are bidding for their fourth straight league championship and 12th in coach Ron Cohen's 26 years. The Vikings last won in 1983.

Pick: With Sillman back and revenge in mind, Washington is the popular choice. But we think Chris Riley's bunch finds a way to win a close one. Northeast, 16-14.
