For High School Football Coaches and Fans, a New Digital Blitz

Quentin Hardy:

Time for some Texas high school football, heavily assisted by modern technology.

On a recent 90-degree Saturday night at Heroes Stadium here, with the lights flickering on at sunset, the Knights of Byron P. Steele II High School opened their season before a crowd of more than 6,500.

“I feel good,” said Scott Lehnhoff, the Knights’ coach. “Everybody feels like they’re in the right place.”

If they weren’t, cameras around the field and stands probably would have caught it. And that footage would be part of about 40 hours of digital action that Mr. Lehnhoff studies, edits or shows his team every week.
