WINDHAM — Londonderry High School quarterback Jake McEachern threw for more yards than Windham totaled on offense as he led the Lancers to a 49-3 Division I South road victory on Saturday.

McEachern completed 12 of his 16 passing attempts for 241 yards and three touchdowns and also ran six times for a team-high 71 yards and two scores for the Lancers, who are ranked No. 1 in this week’s Union Leader Power Poll.

McEachern, a senior, ran for a 3-yard touchdown and connected with Tyler Kayo for a 9-yard score to cap Londonderry’s first two drives and help build a 14-0 Lancers advantage. He also hit Cole Keegan and Alex Tsetsilas for TD passes of 21 and 14 yards, respectively, in the second quarter and ran in a score from 5 yards out in the third quarter.

“He’s been phenomenal,” Londonderry coach Jimmy Lauzon said of McEachern. “Some of the passes — even the ones that we dropped out there — were unbelievable passes ...We’re seeing the field the same way, which is important. He’s just very prepared every week and he’s very just calm, cool and collected and the big moment never gets to him.”

Lauzon has been especially impressed by McEachern’s accuracy this season.

“We knew he could run, we knew he could make all the plays,” Lauzon said. “It’s just his accuracy has just been unbelievable so far.”

Londonderry (5-0) led 35-3 at halftime, scored on each of its first seven drives and outgained the Jaguars (2-3) 449-144 on offense. The only real blemish for the Lancers was the 95 yards they gave up on 11 penalties. The Jaguars were penalized twice for 15 yards.

Londonderry running back Jeff Wiedenfeld (13 carries, 58 yards) ran in a 1-yard touchdown and McEachern’s younger brother Dylan, a junior, capped the game’s scoring with his 19-yard run to the end zone that came with 5.6 seconds left in the third frame.

Zach Fawcett made each of his seven point-after kicks for the Lancers.

“Linemen (were) just creating holes for us, for our running backs and receivers got open, really,” Jake McEachern said of Londonderry’s offensive success. “Just trying to find the weaknesses and get open, drive down the field for a touchdown.”

Windham entered the Lancers’ red zone on one drive, which concluded with Adam Burke’s 24-yard field goal that cut Londonderry’s lead to 28-3 with 3:19 left in the first half. That drive, which covered 67 yards on 13 plays, was Windham’s longest of the game.

Windham junior quarterback Rocky Heres went 5 of 10 passing for 49 yards, threw an interception and ran 11 times for 30 yards. Riley Desmarais led the Jaguars in rushing with 41 yards on 13 carries. Cole Peterson logged two catches for a team-high 22 receiving yards for Windham.

“Believe it or not, we love these weeks,” Windham first-year coach Jack Byrne said. “We want to be in coaching battles and we lost this one (Saturday). We got outcoached, we got beat on the field but that’s not a knock to our guys. We coached as hard as we could against a great coaching staff who, man, they just find the right things. They’re a few steps ahead of it seems like everybody right now so we’ve got to give them credit and tip our cap.”

Dylan McEachern ran for 55 yards on six carries. Keegan recorded a game-high 128 receiving yards on five catches. Tsetsilas had four catches for 74 yards and Kayo logged two receptions for 26 yards. Defensively, Londonderry received a sack and a team-high five tackles from Riley Boles and an interception from Keegan.

“(Windham is) really good defensively and they just gave us some favorable looks at times so we took advantage of it,” Lauzon said. “(Byrne is) going to do a good job at Windham and he’s just kind of changing the culture of things so we just kind of caught them at the right time and were able to execute really well at times.”
