Pick: Garnet Valley, 28-17.
No. 15 Pennsbury (8-3) at No. 10 Coatesville (9-2), 7. Pennsbury's wing-T offense is headed by bulldozing fullback Daquan Mack and shifty halfback Adam Lewis.
Coatesville likes to open things up, with Manny Stocker handing off to Dae-Hon Cheung or throwing to speedy wideouts Kyle Kerrick and Chris Jones.
Analysis: The difference will be up front, where the Falcons have bigger, more physical players.
Pick: Pennsbury, 24-21.
No. 14 Neshaminy (8-3) at No. 11 North Penn (9-2), 7:30. Tailback Sean Ulmer (1,205 rushing yards, 12 TDs) and southpaw QB Joe Bianchino hope to give Neshaminy its first win against the Knights since 2007.
For North Penn, handyman Dan Gevirtz and tailback Kyle Mayfield have fared well running behind linemen John Garland and T.J. Smink.
Analysis: The Knights have been on a tear lately, winning their last eight games by a combined score of 290-71. Look for it to continue.
Pick: North Penn, 31-14.
District 1 Class AAA Semifinals No. 5 Strath Haven (8-3) at No. 1 Pottsgrove (9-2), 7.
For the Panthers, who use a wing-T scheme, James Griffin (1,055 rushing yards, 13 TDs) and fullback Andrew Crawford (641, 10) are the driving forces.
Since tailback Mark Dukes (1,043, 9) went down with a broken ankle, Pottsgrove has relied heavily on QB Tory Hudgins and fullback Bobby Curtin.
Analysis: Strength of schedule will be a factor here. The Panthers were toughened while playing the likes of Garnet Valley and Ridley.
Pick: Strath Haven, 26-14.
No. 7 Academy Park (8-3) at No. 3 Phoenixville (8-3), 7. The Knights need another big effort from wideout-turned-running back Mark Doe and backfield partner Caleeh Jeffrey.
Phoenixville also relies heavily on the run, with fullback Vinny Nattle (1,180 rushing yards, 9 TDs) and QB Alec McQuiston (554, 7) leading the way.
Analysis: This one is a toss-up, with turnovers probably being the difference.
Pick: Phoenixville, 27-23.
District 1-12 Class AA Subregional Final No. 4 West Catholic (8-3) at No. 2 Springfield, Montco (11-0), 7.
David Williams (1,53 rushing yards, 16 TDs) and the Burrs nearly had their bid for another state title end last Saturday against Bok.
The Spartans' breakthrough season has been ignited by Clay Ewell (1,340 rushing yards, 16 TDs), QB Doug Bauer (42 for 80 passing, 930 yards, 15 TDs), and handyman Tim Quigg.
Analysis: West's close call against Bok is cause for worry, but the Burrs have too much speed for Springfield.
Pick: West Catholic, 28-7.
Saturday Doubleheader at Northeast.
District 12 Class AAA Championship Game Dobbins (9-2) vs. Archbishop Wood (10-1), noon.
Dobbins must find running room for Daquan Brown and Jameel Davis. Wood has outscored foes by 487-88.
Analysis: Wood has gained its last three district crowns by a combined 142-20. Enough said.
Pick: Wood, 55-0.
District 12 Class AAAA Championship Game George Washington (8-2) vs. La Salle (10-1), 4.
The Eagles "shocked the world" in 2008, beating La Salle, 23-14. They'll need a monster effort from Hakeem Sillman to do it again.
The Explorers, in looking to get back to the state final, must iron out some kinks on offense.
Analysis: While Sillman has been superb vs. Public League opponents, we don't see him doing much damage in this one.
Pick: La Salle, 30-7.
