The No. 8 Razorbacks (6-1, 2-1) rallied from their second 17-point or more second-quarter deficit on Saturday, when they tossed aside a 17-0 Ole Miss lead to down the Rebels 29-24.
"We re-evaluate everything," Petrino said. "I don't think that they correlate together – the A&M game and the Ole Miss game because there were a lot of differences in how we started. But we need to do a better job starting out.
"What I look like at is the positives, though," Petrino added. "I like the way we played, the way we competed, the energy that guys gave us on the sideline when we were behind and that we found a way to win."
"There is a lot of people that want to talk about other things that are wrong, all the negatives," Petrino said, "which I understand, that is a part of the business, but I like to look at the things that are positive. Our toughness, our character, our heart and really the thing that showed up so much at halftime and in the second half is our competitive spirit and the fact that our leaders stay positive.
"I've been in situations before where with certain teams, it doesn't go that way," Petrino added. "It goes the other way. We have not been that way. We have been very positive and our leaders have been good and encouraging. That is the one thing that shows up in leadership on our football team so well. We have guys that encourage and help other guys play better and I am proud of that."
Petrino also made it clear that he doesn't want to give Vanderbilt (4-3, 1-3) that kind of head start this Saturday when Arkansas visits for an 11:21 a.m. game.
"What gets their attention is when you put the video on and you watch them on video and see how well they play the game," Petrino said. "They play good defense, they know exactly what their package is, they are physical and offensively they way they can execute. We have to go play a good football game and play hard and play fast and do things right to win the football game. There is no doubt about it."
Senior defensive end Jake Bequette concurs.
"Like you saw Saturday, if you don't bring you're a game you have a chance of getting beat by anybody," Bequette said. "Vanderbilt is no exception."
Bequette knows Arkansas can't afford to rely on its comeback ability each week.
"That really falls on the leaders of this team, including myself," Bequette said. "I need to help get the team ready to play faster from the opening whistle. I know we were ready to play on Saturday, but for some reason in the last three or four games, we haven't started very fast.
"We really kind of dug ourselves in a hole, which isn't very good," Bequette said. "We would all prefer to get to a big lead and keep a big lead, but football is a game of adjustments and momentum. We've been able to overcome some early deficits. We have to figure out why we're starting slow and correct it."
Like Petrino, Bequette is proud of the adjustments that his team is making at halftime.
We've made some really good second-half adjustments in the last three or four games," Bequette said. "That's really a credit to our coaching staff and our players who are seeing the little things that give us an advantage. It has to be on us to start fast because we always have a good game plan going into the week, but we just have to execute it."
The Commodores, under first-year head coach James Franklin, are coming off a 44-21 win over Army on Saturday.
"I think he is doing a really nice job," Petrino said of Franklin. "You turn the video on and you see how well-coached they are. They have a scheme they believe in. That is what they are working at, that is what they are executing and their players are playing extremely hard."
They have been tough at home this season, going 4-1 with a 30-7 pounding of Ole Miss and a close loss to Georgia (33-28) among those contests.
"It is going to be another hard-fought contest," Petrino said.
Vanderbilt's offense is led by quarterback Jordan Rodgers, the younger brother of Green Bay Packers signal caller Aaron Rodgers.
He was 10-of-27 passing for 197 yards against Army while also rushing 18 times for 96 yards.
"He is a great athlete," Petrino said. "He can really run and they utilize him in the run game. When I watch him throw, he has a quick release and a strong arm. Certainly a dual threat that we have to do a good job of understanding what they are trying to do with him. It is going to be important for us to play fast, really run to the ball and tackle right from the start."
Tailback Zac Stacy had 21 carries for 198 yards and three touchdowns against Army.
Petrino noted that Ole Miss and Vandy's offenses are different.
"They are different in styles," Petrino said. "Vanderbilt uses the spread option offense. They really do a nice job with it. They do have a number of quarterback-called runs where they block run plays as if you were handing the ball to the tailback, but they just directly snap it to the quarterback and the tailback is the lead blocker…They make you defense the option game, both the read option and the speed option so you have to be very disciplined with your assignments, yet still play fast."
Bequette expects Arkansas' defense to post a gem sometime soon and hopes it's Saturday.
"We really haven't tapped our potential yet," Bequette said. "We have got to play that A game. When we do it is going to be something special."
Petrino has also been impressed with Vandy's defense.
"They are a good defense and run a very good blitz package," Petrino said. "They are not afraid to bring pressure. They blitzed Georgia more than they did anybody else. They were up in the high 60s percent. That was extremely high. You don't see someone blitz 68 percent of the time. That is what they did and they did a good job of it.
"We are going to have to do a good job on our execution and really knowing what we need to do and find out what their tips are," Petrino said.
