DALLAS -- Sometimes, winning your first game doesn't mean you played well -- just that you didn't play as poorly as the other team.
"My dad's an old coach," said Brent Whitson, South Grand Prairie head football coach. "And my dad used to say -- if we won one early -- he'd say, 'They just out-sorried us.'"
It's hard to prep for that first time on the field.
"You try to create intensity in practice, and you try to create as much chaos as you can in practice," said Argyle Head Football Coach Todd Rodgers.
In a high school team's first game of the year, referees are involved for the first time and so are penalty flags. Sometimes, a lot of them.
"We had some normal penalties you have in early ball games -- kids jumping off side and not being set," said Frisco Wakeland Head Football Coach Marty Secord said of his team's opener.
Rules continue change and evolve. What's a penalty now may not have been a penalty 10 years ago. One thing Frisco Independence works on, in particular, is sideline hits, and making sure their players are in bounds when they make contact.
"A lot of kids will come to tackle somebody, and they won't realize they're out of bounds, and they'll hit them late and get you a 15-yard late hit," said Frisco Independence Head Football Coach Kyle Story. "So, we try to train them up on when they cross that sideline."
A couple of coaches told us the biggest improvement comes between games one and two.
"Really great teams improve the most between one and two, and that's what we look for this week," Whitson said about his SGP team.
Coach Rodgers from Argyle pointed out that NFL teams need weeks of training camp and four preseason games to get ready for a season.
"It just takes -- even the adults, the professionals -- an extended amount of time to be good," Rodgers said.
That process continues this Friday night.
