"We had a good week," he said Thursday after a workout in the stadium. "We had good focus and had our best effort. Today went well. We prepared very well this week.
"It's been a good week of practice. They did a nice job."
Petrino knows what he wants to see Saturday night when the Hogs meet the Tigers at 6 p.m. at Reynolds Razorback Stadium.
"It's good to be back home and we really need our crowd to give us a big lift," he said.
And he wants the kind of physical play that his players provided in the second half against Texas A&M when the Hogs outscored the Aggies, 25-3.
"It's up to us to play physical like we did in the fourth quarter last week," he said. "We were able to run the ball because of the way we hit. We need that again."
Petrino sees competition again at running back where Ronnie Wingo is trying to hold off Dennis Johnson and Broderick Green for playing time.
"Wingo is doing fine," Petrino said. "He's doing some good things. This week, Dennis looked as fast as he's looked since he came back. He has better acceleration this week. I think he got confidence from the way he played last week and he's getting better and better."
Petrino has said several times in the last week that he is surprised that Green is back after having ACL surgery last spring.
"I was apprehensive when they started talking about it," Petrino said. "He beat all of the projected times for coming back. He's done a good job in practice the previous two weeks, but he looked even better this week. His instincts are very good. His vision is back. He is cutting real well."
It's hard to scrimmage during the season, but Petrino said there are multiple drills that focus on tackling. And the Hogs needed to get better at tackling. They struggled against Alabama and during the first half of the A&M game. Tackling improved in the second half.
"We did do a lot of work on tackling, but I think it was better in the second half last week," he said. "We addressed that (at halftime). We improved. We had been tackling low. I don't think you can tackle a good back low. You have to hit them high.
"We worked on tackling circuits this week. We worked on shedding blocks. We continue to cover the fundamentals, where you position your eyes, your hand positions. We cover those things every day."
Petrino wants fewer penalties.
"We've addressed that," he said. "Fourteen is too many. It wasn't all offense. What I don't like were the personal fouls."
Offensive tackle Jason Peacock, the starter last week on the weak side instead of Mitch Petrus, has had a few penalties.
"He's doing a nice job," Petrino said. "He's working to stay focused and he's gotten better every week."
