Here's a quick look at some of the biggest story lines in the first round of the high school football playoffs.
The Main Attraction
No. 10 Edmond North (6-4) vs. No. 6 Edmond Memorial, 7 p.m. at Wantland Stadium
*The plot: The Edlam series of games between the three Edmond schools has become one of the best-known big-school rivalries in the metro area. And the stakes can't be much higher than a win-or-go-home Edlam showdown.
Memorial won the season opener, 13-0, but the North offense has picked up steam since then. Still, the story of this game will be told by the defenses. Together, these two teams have held 16 of their 20 opponents to 21 points or fewer.
*The pick: Edmond Memorial 20, Edmond North 17. Memorial has the best offensive player in the game with running back Warren Wand, who averages 170 rushing yards and has scored 15 touchdowns. In such a tight defensive battle, one or two big plays from Wand could turn the tide. Of course, Edmond Memorial has the always difficult task of trying to beat a team for the second time in the same season.
Contenders or pretenders?
Three teams with the talent to go deep into the playoffs, but a matchup that could send them home Friday night:
*Woodward (7-3): Perhaps the best defense in Class 4A, but QB Kale Hixon was injured in last week's 19-14 loss to defending champ Clinton. His health will play a big part in determining how far the Boomers can go. With or without him, winning at Ada in the first round won't be easy.
*Cushing (8-2): The regular season ended with a whimper for Cushing, which had been in the top five virtually all year. Losses to Seminole and Bethany have the Tigers reeling, and now, they have to go on the road against a Jones team that has been stout on defense. Cushing RB Gage Stallworth is a difference-maker, and the Tigers will need every yard he can grind out.
*Thomas (9-1): The fifth-ranked Terriers have been impressive, especially on defense, most of the season, but drew a scary matchup against an incredibly talented Texhoma team that just hasn't put it all together yet. If the Red Devils are able to hit the switch for the postseason, it could be bad news for Thomas.
Names to know
Three players to watch in crucial first-round matchups:
*Dahu Green, Westmoore: Physically daunting and athletically gifted, the 6-foot-3, 185-pound receiver is a big play waiting to happen. Green had Westmoore's only TD, an 81-yarder, in a 20-10 loss to Broken Arrow last week, and he'll be looked to for more big plays on the road against a tough Sand Springs secondary Friday.
*Kyle Duke, Bethany: Tuttle was ranked in the top 10 much of the season, so despite the fact that Bethany is the host team against the Tigers, Bethany might be playing an underdog role. QB Kyle Duke sparked the Bronchos' upset of Cushing last week and will be the focal point of the Tuttle defense.
*Chandler Garrett, Mustang: Garrett's emergence at quarterback has strengthened the move of Frankie Edwards from QB to running back. As dangerous as Edwards is with the ball, the added dimension of the sophomore Garrett as a pass-or-run threat opens up the offense and will be vital if the Broncos hope to go on the road and upset Norman North.
