Ted Davidson’s been a part of Acadiana High’s football program for more than three decades, the last 10 as head coach, and can’t reasonably explain it.

During its rise to statewide prominence that’s included six trips to the Class 5A state championship game and three titles, the Wrecking Rams have developed a penchant for launching their deep postseason runs from Bill Dotson Stadium.

Acadiana has reeled off an impressive stretch of 20 consecutive victories dating to 1999 from the comfort of its home field — a place the No. 15-seeded Rams (9-4) hope to enjoy again when No. 3 Zachary (12-1) visits for Friday’s Class 5A state semifinal at 7 p.m.

“We’ve talked about having the privilege of hosting a playoff game and to make the most of it,” said Davidson, who won his 100th game at the school (100-31) in last week’s 28-14 semifinal win over Mandeville. “They take a lot of pride in playing at home in the playoffs and protecting the house. But it’s not going to do us any good Friday if we don’t play well.”

Included in Acadiana’s staggering streak are three wins over Zachary. The Rams ended the Broncos’ season in three of the past four years by a combined score of 187-70.

Zachary returns to Acadiana, for the first time since a 49-7 regional loss in 2012, a well-rounded team.

First-year coach David Brewerton, who led Livonia to the Class 3A state title game last season, has brought a more physical approach to the Broncos, especially on defense.

Brewerton knows that unit will have its hands full trying to slow down Acadiana’s option-based veer attack that’s led by Tulane commitment Malik Eugene (141-1,095 yards, 13 TDs), Eric Duhon (139-762, 8 TDs) and Donavin Solomon (85-694, 8 TDs).

“They are not going to try and trick you in any way, and what you see is what you get,” Brewerton said. “It’s a matter of whether you can stop it. For the last several years, they’ve had some great football players and great teams, and nobody could stop them. The question’s going to be is how long does it take our defense to get adjusted to it?”

Zachary’s offense offers a complete contrast to that of Acadiana, relying on a fast-paced spread system that features quarterback Lindsey Scott Jr., who has accounted for more than 3,000 yards total offense and 37 touchdowns.

Scott has completed 127 of 215 passes for 2,137 yards with 23 TDs and six interceptions. Douglas Coleman serves as his top target with 48 catches for 822 yards and seven scores.

Middle linebacker Kevin Moore, who is 4-0 as the team’s starting quarterback, leads Acadiana defensively with 137 tackles, while Davidson said the Rams are currently getting excellent play from defensive tackle Seneca Malveaux, defensive end Javonis Isaac and free safety Jayrin Wilson.

“The Scott kid has a lot of speed and can hurt you both with his legs and with his arm,” Davidson said. “He has a great field presence and can find people open when he scrambles and can turn it and go. He’s a tough guy to corral. It’s going to be a challenge for us defensively, but they’ve been playing real good football through the playoffs.”
