Tailback Marquis Barefield fuels Pottsgrove's veer option offense, which is averaging 44 points. The 5-foot-8, 150-pounder has carried the ball 100 times for 976 yards and 14 touchdowns.
In last week's 52-14 thumping of Phoenixville, Barefield turned seven carries into a career-high 201 yards and five TDs.
The Falcons, who have won 21 straight league games, also can turn to quarterback Riley Michaels, fullback Sene Polamalu, and receivers Michael Fowler and Jalen Mayes.
Rasaan Stewart, a dual-threat quarterback, leads of Perkiomen Valley's no-huddle, spread attack. A Division I-A prospect as a defensive back, he has passed for 1,057 yards and 16 TDs and run for 743 yards and 11 scores.
The 6-1, 185-pound Stewart gets support from running backs Mark Bonomo and Ryan O'Donnell, and receivers Dakota Clanagan and Clay Domine.
Pottsgrove's defense, allowing only 8.6 points per game, is spearheaded by linemen Nico Demetrio and Anthony Pond, linebackers Jeff Adams and Tyrone Parker, and backs Barefield and Fowler.
For Perkiomen Valley, a defense that has posted four shutouts is keyed by linemen Seth Jonassen and Anthony Pachella, linebackers Anthony Rotondo and Austin Gansz, and backs Stewart and Liam Grande.
We expect the Vikings, with their defense playing a leading role, to win and forge a three-way tie atop the PAC-10 standings.
Pick: Perkiomen Valley, 20-14.
Last week: 9-1. Overall: 66-17 (.795).
