Arkansas quarterback Casey Dick struggled to complete passes for the second straight week in Arkansas’ 52-10 loss to No. 7 Texas.

One reason was that he spent most of his time on the run from the Longhorns’ defensive line. Dick was sacked a season-high six times Saturday and the Longhorns turned in a seven-sack performance against the Razorbacks.

It ran the number of sacks Arkansas has allowed in four games to 17.

The Razorbacks now hold the dubious distinction of being the team that has allowed the most sacks per game in the nation.

Arkansas is surrendering 4.25 sacks a game and is 119th in the country in the category.

“They did a good job of getting through our offensive line,” Dick said. “We’ve got to be able to execute better. Maybe change the protection here and there. But we’ll try to take a look at it, get things sorted out.”

Dick shared the responsibility for some of the sacks by not getting rid of the football quick enough and making slow decisions.

But Arkansas coach Bobby Petrino said the offensive line had its share of problems, too.

Petrino said Saturday’s problems had little to do with elaborate blitz packages or schemes that fooled the Razorbacks’ offensive line.

“Some of it was blitz,” Petrino said. “Some of it was just one-on-one matchups. Particularly early in the game. We got hit early. They made one-on-one pass rush moves and got in the backfield. They got us once with the corner blitz. ... They didn’t try to do anything fancy.

“They lined up and played their techniques and overpowered us a little bit.”

Sticking With Casey

Petrino may have turned to true freshman Tyler Wilson for the second straight game, but he gave no indication that he’s considering benching Dick after Saturday’s game.

Dick completed just 7-of-13 passes for 138 yards. He also fumbled twice. One of those was recovered by the Longhorns and led to a touchdown that gave them a 31-3 lead.

“Casey allows us to execute or work more of our offense,” Petrino said. “(Wilson) is not familiar with the entire offense so that makes it a little more difficult. We felt like Casey gives us the best chance to execute your offense and move the ball and win games right now.”

McCoy Impresses

Texas quarterback Colt McCoy left a strong impression on the Razorbacks’ defense after throwing for three touchdowns and rushing for two more in the Longhorns’ big win.

“He’s the best quarterback I’ve seen,” linebacker Jerry Franklin said. “His team is pretty good, but he makes a lot of plays.”

McCoy completed 17 of 19 passes for 185 yards. He also ran for 84, including a 35-yard touchdown on an option play that broke Arkansas’ back late in the second quarter.

“He’s awfully good,” defensive coordinator Willy Robinson said. “He made our guys on the back end look real slow on that long touchdown. He did a great job.”

Aguirre Fills In

Backup tackle Michael Aguirre spent most of the second half on the field in place of starter Ray Dominguez on Saturday.

Petrino said Dominguez was slowed by an ankle injury he sustained in practice last week. It was enough to keep Dominguez sidelined during Thursday’s practice.

“He tried to tough it out and play in the first half,” Petrino said. “Aguirre took a bunch of reps during that week. That’s why he went in.”

New Starter

Jerico Nelson became the ninth true freshman to start this season when he lined up at strong safety against the Longhorns.

Nelson replaced Dallas Washington and Matt Harris, who started the first three games at the position. He finished with six tackles.

“There’s some liabilities about some of his play, but it’s easy to correct,” Robinson said. “It’s a matter of him getting confidence with what he needs to do.”

Rivalry Embarrassment

Petrino said the new batch of Razorbacks understood what playing well against Texas means to Arkansas. But it couldn’t keep the Hogs from suffering their third-worst loss — a 42-point margin — in series history.

“We understand the guys from the 1964 championship team that had to beat Texas to win it,” Petrino said. “And the pride they have and the pride that the University of Arkansas has in its football program.

“So it’s not something we’re proud of to come down here and get beat like we did.”
