How big is tonight’s district football championship between Eudora High and Mill Valley? Big enough to postpone Halloween.

Well, almost.

“No, they mostly did that because of the traffic,” Cardinals coach Gregg Webb said of Eudora city officials’ decision to push back the annual trick-or-treat celebration a day to Friday. “They didn’t want the kids out walking around with the traffic problems. It was a safety issue.”

Still, there’s no denying that the 7 p.m. game in Eudora will be one of the biggest around. Both teams are unbeaten in district play. Eudora is 7-1 overall, while the Jaguars are unbeaten. Mill Valley is ranked No. 4 in 4A, while the Cardinals are No. 5.

The winner gets to play host to a first-round playoff game on Tuesday, while the loser goes on the road. Eudora wants to stay at home for at least another week.

“Nobody in 4A wants to saddle it up on a Tuesday and go on the road,” Webb said. “We really need to win this game and stay at home.”

To do that, Eudora will have to stop Mill Valley’s potent rushing attack, which features four excellent running backs and a mobile quarterback. The Jaguars racked up more than 500 yards rushing in their opener and haven’t looked back since. Each back  John Goodin, David and Max Woods and Chris Vanlerberg  is capable of busting a big run, which means the Cardinals have to focus on wrapping up on defense.

“When we don’t miss assignments, sometimes we’ve had trouble wrapping up,” Webb said. “If you don’t wrap them up, they could break one.”

Of course, the Jaguars have to worry about Eudora’s potent rushing attack, which features seniors Andrew Pyle and Tyler Jackson. The Cardinals average nearly 400 rushing yards a game, 277 of which come from that pair.

And that’s from an offense that’s still learning all its schemes under first-year coach Webb. At the start of the season, the offense hit its blocking assignments 20 percent of the time. Now, it’s up to about 60 or 70 percent. With a few more games, Webb thinks his crew could be unstoppable.

“When we can get the percentage up to 85-90, that’s when we’re going to be really good. I just hope we have time to get there,” Webb said.
