Senior Nigale Cabell (5-foot-11, 235 pounds) and junior Shamar Ingram (5-10, 245) form the core of Huntington's defensive front at defensive tackle while inside linebackers Matt Shaver (5-11, 190) and Greg May (6-0, 220) and All-State free safety Clark Wilson (6-0, 180) serve as the remainder of Seals' version of a keystone combination.
May is a senior. Shaver and Wilson - also the team's starting quarterback - are juniors.
"All 11 of those guys on defense have a huge desire to get to the football," Seals said. "They're also very, very coachable. I'm a firm believer that your program takes the personality of its coaching staff.
"We're a very demanding coaching staff. We expect a lot of effort from our guys, and I think it's the same over at Midland. Luke (Salmons, the Knights' third-year coach) is doing a really good job with his guys and I think they've taken on his personality too."
Huntington has allowed 14 points through three games, the lowest total and average per game of any team in Class AAA. The Highlanders will face the football version of a runaway train in the form of Midland's running attack, led by senior Kasey Thomas (6-0, 185) who has 444 rushing yards and nine touchdowns.
Alex Childers (5-10, 160) has run for 295 yards and two scores, fullback Teran Barnitz (6-0, 215) has 273 yards and three TDs and Dontae Hendricks (5-10, 170) - a Huntington transfer - has 218 yards and has reached the end zone three times.
"We can't give up any big plays," Seals said. "We also can't let them get anything over the top with the pass when a safety wants to bite on the run."
Seals said it is too early to put much stock into playoff ratings, but added that the transformation through five years to this point has been impressive to see.
"Our school is electric right now," he said. "That's all the kids want to talk about. Our student body's done a tremendous job of supporting us, and I know they will again on Friday night."
Midland has won both meetings between the schools since Salmons took over the Knights program in 2011. The Knights won 14-13 last year in Huntington and 31-30 the year before in Ona.
