Fenwick coach Dave Woods expects this game to be the toughest challenge his team has faced all year.
"We talked to our kids about bringing our best effort on every single play. If we can sell out and give 100 percent effort, we have a chance. If we don't, I'm not so sure we have a chance," Woods said.
"We have to swarm to the ball. They have a lot of backs (who) can break tackles and run through them. Their O-line gets off the ball and they're big. We have to get 11 guys to the ball every play. The kicking game is a huge part. Hopefully, we can make something happen with our returns and limit them in theirs."
Abington (9-1) is a big, physical team that runs a Wing-T offense, capable of attacking from all angles.
Seniors Al Freeman and Jason Halpin and sophomore Shawn Donovan are the Green Waves' primary ballcarriers. Donovan has scored 14 touchdowns this season and is a threat in the kick return game.
Kelliher admits that his team is run-first, but it can change the pace of the game and will keep defenses honest.
"I think that we've evolved, like other teams," Kelliher said. "We're going to look to rush the ball as much as we can, but we'll also keep you off guard and not keying on the running game by putting the ball up sometimes."
Junior quarterback Bryan Dwyer is a capable passer for the Green Wave with a couple of good targets in tight end Jake Quinlan and receiver Vin Picardi.
Woods knows the Green Wave will be tough to stop offensively and also difficult on the other side of the ball as well.
"We've watched a ton of film on them and they're the best team we've faced all year. That's how it should be when you get to this game," Woods said. "They have great goal line and short yardage defense. We have to get more creative in those situations because we can't depend on Rufus or Nick breaking tackles."
