Those who studied Josh Fields in pregame warm-ups knew Oklahoma State’s quarterback would have a big day Saturday at Memorial Stadium.

“Coach Gundy (Mike, assistant head coach) said he was throwing BBs,” OSU head coach Les Miles said after Fields fired a school-record six touchdown passes in the Cowboys’ 55-20 drubbing of Kansas.

Physically, the 6-foot-1, 210-pound sophomore looked sharp during late-morning passing drills.

Mentally, too.

“I was acting kind of goofy. It was a weird feeling. I was messing around, joking around,” said Fields, who completed 17 of 27 passes for 354 yards. “I was running around and singing, doing stuff like that. I was really relaxed for some reason.”

Maybe because he was facing the lowest-rated defense in the Big 12 Conference – a unit that made the questionable decision to employ single coverage on junior receiver Rashaun Woods, who scored on receptions of 27, 69 and seven yards in the first 14 minutes.

“On the first touchdown I looked out there twice. I couldn’t believe they did that,” Fields said of KU’s coverage.

“Not many people do that. We took advantage of it,” said Woods, whose 69-yard catch was a career-best. “In previous weeks our running game was successful so they were in the blocks. It gave our receivers an opportunity to go deep.”

Woods finished with seven grabs for 171 yards.

Fields’ six TDs passes better the old school record of four, set three times. His 394 passing yards marked a personal best and third-best mark in school history.

“We were really clicking,” said Fields, who also connected with John Lewis and Tatum Bell on scoring patterns of 35 and 13 yards.

“We were scoring quickly. It’s easily our best output of the year,” Miles said after OSU piled up 55 points, most since a 62-point outing against Wyoming in the 1988 Holiday Bowl.

The Pokes’ 549 yards of total offense were most since a 605-yard effort against Louisiana-Lafayette in 1998.

“It might have looked easy. It wasn’t. That’s a good defensive line,” OSU offensive guard Sam Mayes said. “It’s wonderful to have those one-and-out drives, (but) I got a little cold sitting there in the second half.”

Oklahoma State had scoring “drives” of 69 yards in two plays, 35 yards in one play and 61 yards in two plays. Also, senior linebacker Terrence Robinson recovered a KU fumble and raced 93 yards for a TD.

“The last 20 yards I felt like I was an 80-year-old man,” the 6-1, 240-pound Robinson said. “I felt worse when everybody jumped on top of me (to celebrate).”

There could have been one more Cowboy celebration. Woods dropped a sure TD pass late in the first half.

“I had it in my hands. The guy was holding me. I think the refs were trying to get it over with. That’s OK,” Woods said with a laugh.

The Cowboys (5-5, 3-3) need one more win to become bowl eligible. OSU plays Baylor and Oklahoma to conclude the regular season.

“We’ll probably use the ‘B word’ more regularly from this point forward,” Miles said.

“We need a victory this week to count six.”
