Boyertown's record-setting offense has been moving up and down the field with video-game-like audacity over the past few weeks.
The Perkiomen Valley defense, meanwhile, has been about as impenetrable as White House security.
Tonight at BASH Memorial Stadium, it will be the Pioneer Athletic Conference's 2013 version of the irresistible force and immovable object as the Bears play host to the Vikings on Homecoming.
The Bears (4-2 PAC-10, 5-2 overall) are coming off a 62-7 rout of Phoenixville in which they put up a school-record 652 yards of total offense. Boyertown leads the area in rushing (309.9), passing (148.6) and total yards (458.5) per game.
"Everything is yards, yards, yards,' Perkiomen Valley coach Scott Reed said. "Watching them on film, they're very balanced between the run and pass. Against Phoenixville, they were very sharp in their execution.
"They're enormous up front; we haven't played anybody that big since Plymouth-Whitemarsh (in Week 1). From an offensive standpoint, I don't see any weaknesses, and that creates a lot of trouble to get ready for.'
The Vikings (5-1, 6-1) counter with a stingy defense that's already pitched four shutouts and is allowing a paltry 4.0 points per game — tops in all of District 1.
"They're very aggressive, and they fly to the football,' Boyertown coach Mark Scisly said of the Vikings. "They run a 3-5 (alignment) better than anyone I've ever seen.'
That unit has posted back-to-back shutouts and given up just seven points in the four weeks since a 14-7 loss at Spring-Ford, PV's only blemish.
Down linemen Tom Jaworski, Tony Pachella and Luke DiElsi have set the tone up front, while linebackers Danny Light, Austin Gansz, Pat Delaney, Dakota Clanagan and Anthony Rotonda spearhead a dynamic effort that's allowed an average of just 89.7 total yards over the past three weeks.
The secondary of corners Liam Grande and Kurran Holland and safety Rasaan Stewart has locked opponents down through the air to the tune of just nine passing yards combined over the past three weeks.
"They're very competitive kids,' Reed said. "They take things personally. They don't want to be the guys that get beat, and they all trust each other.'
The PV defense will face its sternest test in the high-powered Bears — who like Perkiomen Valley run a no-huddle, hurry-up offense.
"You're just going to have to win battles,' Reed said. "Win first down. Win third down. It's all about getting off the field, if you can.'
Senior quarterback Griffin Pasik has come into his own over the past couple of weeks, throwing for consecutive season-highs of 192 yards (in a 49-34 win over Pottstown) and 231 yards (to go along with four TDs, which matched a school record) last week as the Bears' equalled their school single-game scoring mark. The dual threat has also rushed for 232 yards and five TDs during that time frame.
Wideout Nick Brough has erupted for 11 catches for 233 yards and five TDs over the past two weeks, giving opposing defenses a lot more to think about than bruising fullback Cody Richmond, who leads the area with 1,010 rushing yards.
Brough, a 6-foot-3, 200-pound senior, leads the area with 548 receiving yards. He's just 53 yards away from Ryan Repko's school single-season mark of 601 and his 1,057 career receiving yards are 140 shy of Brandon Mason's school record.
"Other guys have stepped up and started making plays, and it adds a whole new dimension,' Scisly said. "It's taking heat off Cody, but he's running so well defenses still have to honor him.'
On the other side of the ball, the Bears are coming off their best effort of the season, allowing 109 total yards and producing three turnovers — including interceptions from Justin Siejk and Dalton Hughes.
"Our defense has gotten progressively better,' said Scisly, praising the work of defensive ends Tyler Zilen and Brad Dardas as well as strong safety Siejk and outside linebacker Mike Murphy. "We've definitely shown improvement each week.'
That said, Boyertown will be hard-pressed to slow down a Perkiomen Valley juggernaut that's averaging 48.0 points per game over its current four-game winning streak.
Stewart has been consistently excellent at quarterback, with Stewart and Mark Bonomo spearheading a deep rushing attack that got a season-high 116 yards from Ryan O'Donnell last week and Clanagan and Clay Domine fronting a dangerous receiving corps
"You can't really just key on one guy,' Scisly said. "There's Stewart, the two running backs and I don't know how many receivers. It's going to be a challenge.
"It's going to be a battle: ours strength versus their speed. They (the Vikings) are obviously the favorites going in, but our kids are excited for the opportunity, and they're going to give everything they've got.'
Which, on the offensive end, has been a heck of a lot lately.
