The Eagles needed a specific sequence of events to occur to claim the top seed in their district.
They needed a win two weeks ago at home and also for Collins to lose to both Woodford County and West Jessamine.
All those things happened.
That means the Eagles (3-2, 3-1 district) will be the top seed from District 7 when the Class 5A Playoffs begin next month.
Southern will get home games in at least each of the first two rounds of the playoffs.
"We are not going to celebrate this too soon," Southern coach Jon Clark said on the Jack Burford Chevy Sports Show.
The Eagles might not know who their first-round opponent in the playoffs will be for two more weeks.
They are well-aware, however, of the challenge they will face this week.
Southern is set for a trip to Danville to take on state powerhouse Boyle County (5-0).
Kick-off is set for 7:30 p.m. Friday.
"We can't be scared of getting off the bus," Clark said. "I think that's one of the biggest things. I think sometimes when you play Boyle County or Covington Catholic or teams like that, you let them win the game before you even show up."
The Eagles had an extra week off to prepare for the undefeated Rebels.
After having a game canceled in the opening week of the season because of COVID-19 concerns, the Southern coaching staff did consider a last-minute addition to the schedule.
Ultimately, they decided not to.
"We felt like it would be better if we pressed pause for a little bit," Clark said.
An open week in the middle of three-game winning streak certainly had its advantages and disadvantages.
Still, the Eagles used the opportunity to focus on fundamentals and also to rest up.
"We practiced three days," Clark said. "We cleaned up some stuff and worked on some things that we haven't had a chance to put in that we haven't gotten to yet."
Southern put together perhaps its best all-around performance of the season against West Jessamine on Oct. 16 in Berea.
The Eagles came up with four interceptions, two by Jonah Farnstrom, and three rushing touchdowns -- by three different players -- in a 35-6 win. Cameron Holbrook, Juan Rodriquez and Stephen Whitehead scored on the ground and Walter Smith and Jayshawn Ethridge had receiving touchdowns.
Sophomore quarterback Cole Carpenter had another solid performance. He completed 12-of-23 passes for 119 yards and two touchdowns with no interceptions. On the season, Carpenter had 709 yards passing with eight TDs and three interceptions.
Smith leads the team in rushing yards (246), receptions (20) and receiving yards (278). He has five touchdowns (four receiving, one rushing).
Farnstorm, Holbrook and Jackson Chambers each have two interceptions on the season.
Boyle County was also off last week.
In the previous two weeks, the Rebels rolled to shutout district wins -- 40-0 over Lexington Catholic and 54-0 over Anderson County.
The Rebels have scored at least 40 points in every game this season and have out-scored their opponents 247-35.
Quarterback Jagger Gillis has completed 56-of-86 passes for 937 yards this season with 14 touchdowns and only one interception. He also has eight rushing TDs.
Will McDaniel has a team-best 435 yards rushing with seven touchdowns.
Cole Lanter had five TD catches, while Luke Sheperson and Coleman Clark each had three TD receptions.
"They don't make mistakes. We need to minimize mistakes. They capitalize on your mistakes," Clark said of Boyle County.
The Rebels rolled to a 42-7 win over Southern last season in Berea.
