No. 9 Allen (Texas) High and No. 60 Southlake (Texas) Carroll had tougher than expected tests but managed to pull through and advance in the Texas state playoffs.
The same can't be said in Ohio, where No. 61 Cincinnati (Ohio) Colerain and No. 85 Middletown (Ohio) High went down and are not out.
And then there's No. 72 Stone Mountain (Ga.) Stephenson. A week after scoring 49 points in a 50-49 loss, Stephenson was shutout and eliminated by Lowndes (Ga.) High, 7-0.
Here's a look at some of the top games in the RivalsHigh 100 on Saturday:
No. 9 Allen 30, Keller Central 17
A bobbing and weaving 41-yard catch-and-run touchdown in the third quarter gave Keller Central its first lead (13-7) and first bit of hope against powerhouse Allen.
In the end, though, experience won out.
Allen, behind the play of quarterback Alec Morris, showed why it is the No. 9 team in the RivalsHigh 100, outscoring Keller, 17-0, in the fourth quarter to get the victory.
Morris threw a TD pass to Cortland Tolbert and scored on a 1-yard run to lead Allen (11-0). Keller Central was playing in its first-ever playoff game.
RivalsHigh take: The only consistent that has come from watching Allen all season is that the team will be inconsistent. Trailing late in games. Winning close battles. This was another example of a tough contest against a quality opponent. It was also another flirtation with a loss. Next week against Trinity if the Eagle try to sleepwalk though the first half it will not be able to mount a comeback.
Southlake Carroll quarterback Kenny Hill threw for 205 yards and ran for 199 - but the Dragons needed their defense to win this one.
Pesky Plano East - perhaps the best 6-5 team in the country - wouldn't go away. And when it got a last-minute interception, it had one more chance.
That's when Southlake Carroll's Jeremy McClenllan had an interception of his own to wrap up the game.
Southlake Carroll trailed 16-9 in the third quarter before tying the game on Hill's 9-yard pass to Peyton Williams. Carroll took the lead for good in the fourth on a 1-yard plunge by E.J. Ezzard.
RivalsHigh take: This was a back-and-forth affair all evening but Southlake Carroll was able to steal the victory and get into the second round. The Dragons nearly breathed life back into Plano East with an interception late in the game but the defense was able to continue to rise up to seal the win.
The expected defensive struggle never panned out. In fact, it was an offensive explosion that was the difference.
St. Xavier scored touchdowns on its first three possessions behind quarterback Griffin Dolle and never looked back.
Dolle completed his first eight passes and finished the game 9-for-10 for 117 yards and three TDs.
RivalsHigh take: St. Xavier officially has the number dialed up for beating Colerain. The Bombers have ended the Cardinals season three of the last five years and have won five of the last six games between the two schools. Dolle's efficient attack early on allowed for the big lead and while the score looks close, St. Xavier physically beat Colerain by much worse.
Lowndes (Ga.) High held Stone Mountain (Ga.) Stephenson to just 155 total yards in the shutout.
Senior running back Mike Moore provided all the offense Lowndes needed, rushing for 123 yards on 22 carries. He had the only score of the game, late in the first half.
RivalsHigh take: We were told in the preseason by a prominent coach in Georgia that you could give Stephenson 11 NFL players and the team wouldn't get out of the second round of the playoffs. Well the Jaguars had nearly 20 Division I players and did not get out of the first round, again. Coaching plays such a major role in high school football and it is never underscored more than when a team loaded with prospects gets beat by a team with only one.
Now this was the Cincinnati (Ohio) Moeller team we've been expecting all year.
The squad looked like the Top Ten team it was just a few weeks ago, scoring touchdowns on six of his first nine possessions, to earn a matchup with St. X in a regional final.
Junior quarterback Spencer Iacovone led the way, scoring three times on 1-yard runs. His 43-yard TD pass to Monty Madaris in the third quarter gave Moeller a comfortable 35-24 lead.
RivalsHigh take: What happened to this Moeller team for the three straight losses? The offense was clicking and the defense made timely stops. All in all it was not a stellar victory but it will likley allow for the Crusaders to jump back into the RivalsHigh 100 before the showdown with St. X.
