They understand the run-and-shoot quite well.

They just don’t use it a whole lot anymore at Kapaa. When Kelii Morgado arrived four years ago, the former Kauai coach implemented the four-wide attack that spurred the Red Raiders to four consecutive league titles.

At Kapaa, which didn’t have the personnel to match the offense, Morgado has gradually adopted a system that takes advantage of bigger linemen and running backs. The result was the program’s first league crown since 1989.

The Warriors will run anything from the spread option under center to the shotgun, but the theme is consistent: mobile linemen on the move, opening holes. Kapaa will test any defense’s lateral coverage by using the option and running off tackle. Going vertical isn’t the Warriors’ game.

That blueprint might be the right one to topple ‘Iolani in the semifinals of the First Hawaiian Bank/HHSAA Division II State Football Championships on Saturday. Kickoff at Eddie Hamada Field is set for 2 p.m.

“I don’t know about that,” Morgado said. “Their level of competition is really high. We’ve had a really good year for us, but we don’t play any ILH schools. I don’t know if we have the right formula for success. I hope so.”

On paper: ‘Iolani enters the tourney as four-time defending champion in D-II, with five titles total.

Coach Wendell Look’s squad (6-4) went 4-3 in the Interscholastic League of Honolulu, losing all three matchups with D-I powerhouses Kamehameha, Punahou and Saint Louis. The Raiders had wins over Radford and Waianae in nonconference play, and gave Saint Louis a battle before losing 42-35.

Reece Foy has passed for more than 1,900 yards with 13 touchdowns, but he also has 12 interceptions. His escapability is a weapon that keeps defenses honest.

The Raiders have relied on the legs of Kody Mento and Jordan Lee, who have combined for more than 900 rushing yards and 10 touchdowns. Look’s balanced approach takes the weight off Foy and helps with clock management when ‘Iolani sits on a lead.

Tanner Nishioka, Sheldon Gallarde, Dane Arakawa, Kasey Takahashi and Lee are reliable receivers in the no-huddle attack.

Kapaa’s dependence on the legs of quarterback John Das and running back Sendreck D‘Sio was tested in last week’s 7-0 win over Pearl City. Bronson Aiwohi stepped into the spotlight with 83 rushing yards on 15 carries.

D‘Sio (6-0, 230) is a bruiser, pummeling defenders for more than 600 yards so far. Das, a 5-foot-11, 190-pound senior, has rushed for nearly 600 yards and scored seven touchdowns.

“We’ve tailored the offense to his strengths,” Morgado said of Das, who runs plenty of keepers behind pulling guards such as freshman Maka Ah Loo (6-1, 305) and D‘Sio.

That devotion to the ground game could work on a hot afternoon at ‘Iolani.

“We’re going to try to keep ‘Iolani’s offense off the field as much as we can,” Morgado said.

The skinny: Kapaa’s defense won’t be intimidated by a run-and-shoot offense, but the efficiency of ‘Iolani’s attack will be something new. The last time the Warriors played off island, they pulled out a 27-26 win over Kalani at Aloha Stadium in the Father Bray Classic. No KIF team scored as many points against Kapaa.

“‘Iolani is the bar to measure to. We want to see where we measure up,” Morgado said.

X factor: Kapaa place-kicker Jonathan Paleka, who made a game-winning field goal against Waimea in the KIF title game, will miss the rest of the tournament to participate in a marching band trip to New York, Morgado said. Paleka, a JV kicker for most of the year, had replaced another kicker who had quit. Now the Warriors will count on Rashan “Turtle” Kuhaulua, the JV’s backup place-kicker, for field goals.
