Oklahoma State 56, Louisiana-Lafayette 3
STILLWATER, Okla. -- Tatum Bell spent much of the game on the sidelines, helmet on his head and arms folded over his chest.
Rashaun Woods didn't do much either, turning in his worst performance since his freshman year.
Oklahoma State didn't even need the Big 12's leading rusher or receiver Saturday night as Darrent Williams returned two punts for touchdowns and reserve Vernand Morency rushed for 189 yards and two touchdowns in the Cowboys' 56-3 victory over winless Louisiana-Lafayette.
"It's nice to know there's some talent across the board," coach Les Miles said. "When someone gets the opportunity to play, they make the best of it, that's the way a good football team goes."
Oklahoma State (4-1) was sluggish at the start, but quickly turned this one into a blowout in its final nonconference tuneup before getting back into Big 12 action next week.
The Cowboys will host No. 16 Kansas State, which is coming off a 24-20 loss at No. 13 Texas on Saturday.
Oklahoma State trailed for the first time since its season-opening loss to Nebraska after Louisiana-Lafayette recovered Bell's fumble and Sean Comiskey kicked a 40-yard field goal late in the first quarter.
The orange-clad crowd of 44,700 went silent as the Cowboys responded with a sloppy seven-play, 10-yard drive that resulted in a punt. Oklahoma State went into the second quarter down 3-0.
But the good times didn't last long for the Ragin' Cajuns (0-6) as the Cowboys ran off 28 straight points in the second quarter.
Morency scored on touchdown runs of 1 and 68 yards, D'Juan Woods caught an 18-yard touchdown pass and Williams returned a punt 78 yards to all but seal the win.
Williams, who came into the game with 80 yards on seven returns, brought back another punt for a score in the third quarter, sprinting 59 yards down the right sideline to give Oklahoma State a 35-3 lead.
The junior from Fort Worth, Texas, set what's believed to be a school record -- Oklahoma State's records only go back to 1959.
"I know that I can take any one of them to the house now," Williams said. "I feel like if I get past the first wave, it's pretty much you and the punter and our coach says you won't be back there if you can't beat the punter."
Morency, a 5-foot-10, 215-pound sophomore, got to play only after Bell was benched late in the first quarter for the fumble that led to the Ragin' Cajun field goal.
Bell, who's rushed for 504 yards and seven TDs on 83 carries this season, didn't get back onto the field after the turnover.
That simply created a long-awaited opportunity for Morency, who arrived in Stillwater following four years in the Colorado Rockies' minor league system. He had only 269 yards rushing and three touchdowns as a backup to Bell and junior Seymore Shaw over the past two seasons.
"It can get frustrating, but that is just life," Morency said. "I just felt like I was getting my mojo back."
Meanwhile, Louisiana-Lafayette hasn't won on the road in eight tries under coach Ricky Bustle.
But the Ragin' Cajuns got a good start on shedding their status as the nation's worst offense, as quarterback Eric Rekieta hit Fred Stamps for a 49-yard pass on the game's opening play.
Rekieta completed his first 10 pass attempts for 108 yards, but his 11th throw was intercepted at the Oklahoma State 5 by Robert Jones.
From there, the Ragin' Cajuns offense gained only 57 yards in the first half. They still finished with 347 yards, about 110 more than their NCAA-worst average of 237.4 yards entering the game.
"We were on top of them for awhile," Bustle said. "The big plays, that's what breaks your back. When you're struggling for each and every breath, you just can't give up those big plays."
Rashaun Woods was essentially a non-factor in his first game since catching a Division I-A record seven touchdowns against Southern Methodist. He finished with two catches for 37 yards, his lowest production in a game since catching two passes for 26 yards in a loss to Oklahoma in 2000.
His younger brother, D'Juan, caught his first career touchdown about midway through the second quarter. The score puts D'Juan only 35 touchdowns behind his older brother.
Since losing to Nebraska in the season opener, Oklahoma State has outscored its last four opponents 198-36. It's the Cowboys best start since 1997 when they won six straight en route to a 8-4 season.
The lone bit of bad news for Oklahoma State came when linebacker Lawrence Pinson, the team's leading tackler, was carted off the field with a broken ankle with eight minutes left in the third quarter. He was injured after his foot got trapped underneath his body as he made a tackle.
It's not immediately known how long he'll be out.
