A little more than two-thirds of the regular season remains, but high school football programs in the OCC-Cardinal Division and City League are beginning their league schedules this weekend.
There are six teams from Division I, Region 3 and four in Division I, Region 2 that are 3-0, seven of which are from central Ohio.
The games are going to start meaning more every week for those teams, but also for those such as 2017 Division I playoff qualifiers Gahanna, Olentangy Liberty and Olentangy Orange, each of which is just 1-2.
Here are five things we expect heading into Week 4:
1. Westerville Central will get its biggest test to date in Pickerington North.
The only area matchup of teams off to 3-0 starts will take place when North travels to Central on Friday, Sept. 14.
Considering the Panthers were Division I regional runners-up last season, their perfect start isn't a surprise.
What the Warhawks have done thus far under first-year coach Brent Morrison, though, wasn't as predictable. They opened with a 19-6 win over 2017 Division II playoff qualifier Whitehall on Aug. 24 and have scored a combined 100 points the past two games.
2. The latest matchup of Hilliard programs, featuring Bradley and Darby, will have plenty of meaning.
Hilliard Davidson completed a season sweep of the programs in its community with a 17-10 win over Bradley on Sept. 7, but both the Jaguars and Panthers are 2-1 with their only loss coming against the Wildcats.
The matchup Sept. 14 at Bradley also represents the OCC-Cardinal opener for both squads in the OCC's only eight-team division. The Jaguars put together a perfect regular season last fall, but one of their toughest league wins came against Darby (21-7).
3. Centennial and Columbus South will be challenged as they look to continue surprising starts.
Two perennially struggling City League programs, Centennial and South, have started strong.
The Stars followed an opening loss by posting back-to-back blowout wins, beating Columbus West 53-6 on Aug. 31 and Africentric 47-16 on Sept. 7. On Sept. 14, they visit Northland, which shared the City-North Division title last season.
The Bulldogs haven't had a winning season since 2006 but have given up just 20 points on their way to a 3-0 start. They play Sept. 14 at Eastmoor Academy, which traditionally has one of the City's best programs.
4. Watterson has a chance to show how far it has come under second-year coach Brian Kennedy.
After going a combined 5-15 the past two seasons, the Eagles posted a 17-14 victory over Orange on Aug. 31 and followed with a 25-20 win over Cuyahoga Falls Walsh Jesuit on Sept. 7 to improve to 2-1.
Watterson will get another test of its growth when it plays Wheelersburg on Sept. 14 at Ohio Dominican. The Pirates beat the Eagles 47-17 last year on their way to winning the Division V state title.
5. Reynoldsburg will try to continue its best start in more than two decades.
After back-to-back blowout wins, the Raiders are 3-0 for the first time since 1995.
Reynoldsburg unofficially leads Division I, Region 2 in computer points and has beaten two teams that are 2-1, and it has another chance to add to its playoff resume when it visits Central Crossing on Sept. 14.
The Comets, who lost to the Raiders 21-7 last season, take a 2-1 record into the matchup with two double-digit victories.
