Freeport coach John Gaillot didn't expect the Yellowjackets to hang 35 points on Shady Side Academy during their Greater Allegheny Conference opener last Friday.

But Freeport's offense, under first-year quarterback Ryan Weigold, made a steady march toward the end zone, wracking up 335 yards of total offense in a 35-7 win.

Gaillot was more surprised when he talked to his offensive coordinator about their balance.

“We were 48 percent pass and 52 run,” Gaillot said. “That's a lot different than last year. We were heavy pass. When we tried to establish the run, we had some routes come open.”

Summit Academy, which will take on the Yellowjackets at 7 p.m. Friday at Swartz Field, went in the opposite direction during its opener.

The Knights scored 18 points without their offense getting on the field. Summit Academy's offense struggled after that in the Knights' 43-18 loss to Highlands.

“We ran out of gas,” Summit Academy coach Steve Sherer said. “It was hot, humid and I think our kids got tired.”

Freeport (1-0, 1-0) will give the Knights another cardio test this week.

The Yellowjackets fun n' gun offense produced 262 passing yards last week. Brandon Hochbein led Freeport with 110 yards on three catches. His brother, Dylan, had 82 yards on two receptions.

Ian Miller led the Yellowjackets in rushing, gaining 61 yards and scoring three times on six carries.

“Our defense is set up, they like to pass and (Weigold) is a good quarterback,” Sherer said. “They do a lot of things well. Our secondary has to play well.”

The Knights' offense will need to handle Freeport's stout defensive line.

Yellowjackets senior defensive lineman Logan Thimons, who is a West Virginia University recruit, collected two sacks against the Indians last week. Freeport finished with 10 tackles for loss.

“Offensively, we have to block,” Sherer said. “We didn't do a good job of blocking last week.”

The Yellowjackets plan to challenge the inexperienced Summit Academy line.

“The kids have to one up what they did last week. We don't want them to regress,” Gaillot said. “We want them to be more physical and more emotional. It's an emotional game.”
