The traditional power wins most of the time in high school football.
But not all the time.
And that what makes Friday nights so special.
Four schools ended long losing streaks, knocking off ranked teams in the process.
Owasso 41, No. 20 Union 38
It's a victory that's literally a generation in the making.
Owasso (Okla.) High used a game-ending 17-play, 90-yard drive to defeat Tulsa (Okla.) Union and end a 25-year losing streak in the game.
And it's not like Owasso is the only one losing to Union.
The victory ends Union's 94-game, 13-year district streak as well.
Trailing 38-34 with 2:38 left, quarterback Kason Kay engineered the historic drive.
It culminated with a 5-yard touchdown pass to Keon Hatcher with 10 seconds left in the game.
RivalsHigh take: This is a pretty big stunner as it looked as though Union was going to cruise through the state to another title and high national ranking. Owasso has long been a baseball power, both in state and nationally, but football has been an up-and-down situation. This is certainly a high.
No. 33 Hillgrove 12, No. 32 McEachern 10
Hillgrove defeated McEachern for the first time in the Battle of Powder Springs. And it won it in a way it may never do again.
With the scored tied at 10 with less than four minutes to play, McEachern was deep in its own territory, ready to punt. The snap, however, went over punter Tyler Smith's head and he was forced to knock it out of the end zone to prevent a potential touchdown.
The resulting safety proved to be the winning points.
The game was far different from the team's 2010 matchup, when McEachern triumphed 64-48 in a game that featured more than 1,100 yards of offense.
RivalsHigh take: The biggest take away from this game is that McEachern was not ready offensively for the big time. The quarterback play was pretty poor and despite having a solid defense, it wasn't enough to get the win. This game was a far cry from last season's track meet and that is a major reason why.
In a victory Redlands East Valley coach Kurt Bruich called the biggest in school history, Redlands East stunned Mission Viejo.
Redlands East Valley won it with defense, limiting Mission Viejo all night and clinching the victory with an interception on the 10 in the closing minutes.
Redlands East Valley improves to 6-0 with the victory and now feels the sky is the limit.
"To knock off a traditional Orange County powerhouse like Mission Viejo is quite a statement," Bruich told the Press-Enterprise.
RivalsHigh take: This is not only bad news for Mission Viejo, a team which will likely fall from the RivalsHigh 100, it is also bad news for Don Bosco, a team in a tight battle for the top spot and needed Mission Viejo to stay the course and win out in California. The SoCal evaluations have been down all season and this furthers the muddied waters.
Old-timers may still find it hard to believe that once-powerful Valdosta had a long losing streak against anyone, let alone a local rival.
After Friday night, it doesn't matter.
Valdosta scored two touchdowns in the final 48 seconds to stun crosstown rival Lowndes, 21-17, and end a seven-game losing skid in the game. It's Valdosta's first victory over Lowndes since 2003.
Valdosta pulled to 17-14 on a touchdown from Shelby Wilkes to Sherrod Inman. Then, after getting the onside kick, Wilkes found Avery Burney for a 35-yard score with 17 seconds remaining for the win.
With the win, Valdosta improves to 6-1 and improves its chances of regaining a spot in the Top 100.
RivalsHigh take: What a final minute and a half of football this was. Valdosta had a third and two with a few minutes to play that converting would have ended the game as a 17-7 win. A touchdown and recovered onside kick made a major difference. The winning touchdown, on a scramble drill play, ignited a celebration for the Valdosta faithful who had to suffer through a near-decade of being beaten.
Jefferson City wasted a 23-7 first-half and blew a chance to win on a last-second field goal.
But it came up big in overtime.
Both teams scored in the first overtime, but Jefferson picked off a pass in the second, setting up its offense.
From there, kicker Ryan Tanner booted the game-winner, ending Jefferson City's 13-game losing streak to Rockhurst.
RivalsHigh take: Rockhurst was a team trending down in the RivalsHigh 100 as poor performances were becoming the norm and not the exception, so this loss is not surprising as Jefferson City was the No. 3 team in the state entering play. While the final score was close, Jefferson City could have run away with it - but it appeared to take its foot off the accelerator once it was up comfortably. The loss will push Rockhurst out of the RivalsHigh 100.
