STILLWATER —  — Oklahoma State uber-booster Boone Pickens spoke for most fans of the Cowboys before their season opener Saturday night against Washington State.

“I’m anxious to see what we’ve got in the way of an offense,’’  Pickens said, noting the off-season hiring of Dana Holgorsen as the Cowboys’ new coordinator and play caller.

Pickens undoubtedly came away satisfied as Oklahoma State rolled up 544 yards in a 65-17 rout of the Cougars. But even after Oklahoma State didn’t commit a turnover, had only four penalties and posted its highest-scoring season opener since 1916, Holgorsen said the Cowboys remain far from a finished product.

“We’ve just got to get better at operating the offense,’’ Holgorsen said. “Whatever they give us, we’ve got to be able to take it.’’

Holgorsen came to Oklahoma State with quite the reputation. He helped Mike Leach construct Texas Tech’s frenetic offense before spending the last two years at Houston, where he turned that program into an offensive force. But with four new starters on Oklahoma State’s offensive line, a 26-year-old quarterback who hadn’t started a football game in nine years and a mostly inexperienced receiving corps, he wondered how quickly the Cowboys could master his intricate offense.

Early on, quarterback Brandon Weeden looked a bit shaky, acknowledging he had “jitters.’’ Then tailback Kendall Hunter took over. Hunter, a third-team All-America selection in 2008, was severely limited last season by an ankle injury. But he looked like his former self against Washington State, carrying 21 times for 257 yards — the 12th-best single-game total in school history — and four touchdowns.

“When you average 11 yards a carry, you probably ought to give it to him,’’ Holgorsen said.

Hunter left the game after the Cowboys’ first series of the second half or he could have threatened Barry Sanders’ school record of 332 yards, set against Texas Tech during his Heisman Trophy season in 1988.

“I am trying to protect (Sanders) a little bit,’’ quipped Oklahoma State coach Mike Gundy, who played with Sanders that season. “We’ll see if he’ll buy a club-level suite if we protect his record.’’

Joking aside, Weeden said Hunter’s success running the ball keyed the Cowboys’ success in the passing game “and made things a little easier for me.’’ Weeden, a former New York Yankees minor-league baseball player, completed 22 of 30 passes for 218 yards and three touchdowns, all to Justin Blackmon, before giving way to freshmen backups Clint Chelf and Johnny Deaton.

Chelf, a former Enid High School star, was four-of-five passing for 29 yards. His brother, Colton, caught a pass for seven yards.

“We’re going to do whatever,’’ Weeden said. “I’ll throw it five times a game or I’ll throw it 50 times a game. It doesn’t matter to me as long as we come away with a win.’’

Except for Blackmon, who had eight catches for 125 yards, no other receiver stood out for the Cowboys. Josh Cooper had five catches, but for only 31 yards. Bo Bowling had three catches for 30 yards. Seven other players had at least one catch for Oklahoma State, but Holgorsen didn’t sound pleased.

“We've got a long ways to go on offense,’’ he said. “I thought Brandon managed the game well. I thought we took care of the ball well. Obviously, Kendall, they had a hard time tackling him, and then we had at least one deep threat in Blackmon. I’m happy with those three guys, but ... we are still looking for about another six guys to step up and become real players.’’

The Cowboys did have an offensive twist not expected with Holgorsen — on a handful of plays, they used a full-house backfield, with three running backs joining Weeden behind the line. Holgorsen smiled when asked about that. He said he and another assistant hatched the scheme this summer during a staff outing.

“It gives you a different way to run the football and use a play-action pass,’’ Gundy said Sunday. “I think it’s taking advantage of the personnel we have and using it to the best of our ability.’’

The Cowboys will host Troy in a 6 p.m. kickoff Saturday. The game will not be televised but can be heard on KNID (107.1 FM) Radio.

Notes: The Cowboys, already thin at defensive tackle, lost starters Shane Jarka and Chris Donaldson to injuries just minutes apart in the first half. Jarka was on crutches on the sidelines in the second half. Gundy said Sunday he thought Donaldson and Jarka would be out for a week or two, and in the meantime, “every tackle we have in the program will have to play ... because you've got to have guys practicing and prepared.’’ ... Twenty-nine players made their debut for the Cowboys on Saturday, including 21 freshmen. ... Kicker Quinn Sharp delivered nine touchbacks from his 10 kickoffs and averaged 45.7 yards on seven punts.
