Michigan State coach Mark Dantonio has been studying Boise State almost since the Spartans’ 2011 season ended.

He called up some video again Monday before addressing the media. He says he has counted 178 different offensive formations used by the Broncos.

“They’re a little bit of an unknown at certain positions because they’ve lost some guys. But they’re an extremely well-coached team,” Dantonio said. “… We’ve grown a lot of respect for them just from the time since we’ve been watching them.”

The Spartans, with two straight 11-win seasons, and Broncos, with four straight 12-win (or more) seasons, meet in the season opener Aug. 31 in East Lansing, Mich.

“All I do is just keep looking at 73-6, which is Coach (Chris) Petersen’s record,” Dantonio said. “You don’t have to go much beyond that.”

• ESPN on Monday announced its on-air crews for college football this season. The Friday crew (Boise State-Michigan State) includes Carter Blackburn for play by play, Rod Gilmore as analyst and Jemele Hill on the sidelines. The Thursday crew (Boise State-BYU) includes Rece Davis for play by play, Jesse Palmer and David Pollack as analysts and Samantha Steele on the sidelines.

CAMP IMPRESSIONS

• In the veterans practice, the first-team offense drove 65 yards for a touchdown on the first game-like possession of camp. Sophomore wide receiver Matt Miller made the TD grab. The defense bounced back by producing three turnovers — its daily goal — for the first time, including a nice interception by linebacker Tommy Smith on a ball that bounced off a receiver’s body.

• In the newcomers practice, true freshman cornerback Donte Deayon — dubbed “Mr. Interception” at Summit High school in Rialto, Calif. — recorded one interception and nearly snagged another in 1-on-1 drills.

SPOTLIGHT ON … DL DARREN KOONTZ

The senior has become the utility man on the defensive line. He did a nice job at end in spring ball but has moved to tackle this fall because the team lacks depth there. He could play both positions this season, depending on need.

“I’ve always kind of been that hybrid, going back and forth,” said Koontz, who is 6-foot-3, 266 pounds. “They’re making sure I know both of them, covering all the ground, so when it comes down to the season I can be prepared to play both.”

Koontz was a part-time player on the Broncos’ loaded defensive line last year, making five tackles. He is expected to take on a much larger role this year.

On Monday, Petersen named him the camper of the day on Broncosports.com.

“Darren had a really nice day,” Petersen said. “He was playing physical and much faster, and he was nice and disruptive today.”

MEANWHILE, AT HAWAII ...

Sean Schroeder has emerged as the No. 1 quarterback for the Warriors. He earned his degree in three years at Duke and transferred to Hawaii as a walk-on. He has two years of eligibility remaining.
