While he did not go as far as Tyler Wilson saying it would be as statement games as he did on Monday, Petrino acknowledged that his offense was ready to grab the opportunity before it.
"It is an opportunity," Petrino said. "I think every game is an opportunity to go out there and play your best and compete and do your best. You only get so many of those. It is one of 14 (games) so let's go have fun and light it up and get after it."
Petrino came into his media briefing on Tuesday feeling good about the way the offense had executed in Friday's mock game and in both practices so far this week.
"We have got two more days to get everything down, how we are going to go out there and execute and we're looking forward to it," Petrino added.
Petrino, who said back-up signal caller Brandon Allen would definitely play on Saturday, has been on both the field and in the booth as an offensive coordinator and assistant coach before in his coaching career.
He will be on the sideline Saturday when the Razorbacks host the Gamecocks in a 6 p.m. game at Reynolds Razorback Stadium in Fayetteville.
"It will be no different than it is every day in a scrimmage, every day in a practice," Petrino said. "You are not sitting down and you don't get to drink Coke all day. It is Pepsi now anyway, right?
"You are just down there among the guys, but you will still be doing the same thing," Petrino added. "It will be fun, it will be exciting."
He said there are advantages to both, but had several clear reasons why he wants to be on the field this season.
"I think there are pros and cons to both," Petrino said. "I thinks sometimes you feel like you can see it a little better up top, but to communicate with Tyler – and I think we have had a real good bond or communication…we have hit it off really well through spring ball and through all the scrimmages and I didn't want to lose that.
"I want to be able to look in his (Wilson's) eyes and have him see me," Petrino added, "and I want to be able to talk to him all the time and keep him at the level that he has been playing at, keep his confidence up, keep him going, be able to go over and talk to the receivers, talk to the running backs. So that is how we decided it would be best for the team."
Petrino said that Arkansas wide receiver coach Kris Cinkovich and graduate assistant Joseph Henry will all be in the booth and communicating with him and offensive line coach Chris Klenakis.
"Coach Cink and Coach Joe Henry are going to be up there," Petrino said. "One guy will be able to watch the front and one guy will be able to watch the secondary. I will be talking to Cink predominately and Joe will talk to K (Klenakis) and then we all communicate among each other."
Like everybody else, Petrino was anxious to see what tailback Knile Davis would look like in last Friday's mock game – one that occurred a year after he suffered a season-ending knee injury.
"I think it was good for him to get in there and have a few plays the other night," Petrino said. "You could tell he was anxious before that. He was walking around two hours before the scrimmage started and trying to get himself mentally ready. I think he is real excited – as is everybody else – but I think he may be more excited since it has been a year since he has been out there."
As for number of carries for Davis on Saturday night, Petrino said that is in the yet-to-be determined camp at this point.
"That will just kind of me something that we play by ear, how he is playing and how we are playing," Petrino said. "There is not going to be a pitch count so we are just going to go out there and play the game and see how it goes."
Brandon Mitchell, the former back-up quarterback has emerged as a starter at wide receiver after an impressive camp.
Petrino said that Mitchell has greatly improved his getting off the line of scrimmage since the start of camp and that just adds into what he already was bringing to the table as a wideout.
"He is really smart," Petrino said. "He can see coverages, where they are weak if they are playing zone. He just continues to improve on his get off, has great hands and I think he will make a lot of plays for us."
Petrino also talked about how freshman wide receiver MeKale McKay had won his starting spot this Saturday by simply getting it done in practice.
"He has caught a touchdown in every scrimmage, gave great effort, worked hard and became dependable," Petrino said. "The coaches believe in him, the quarterbacks believe in him. It is still an ongoing fight though. There are still about three or four guys that are fighting for a position every day. But right now he is the leader. It is not over. It will be a continued fight every day."
The offensive and defensive coaches have both laid claim to Kiero Small, who is listed on the depth chart as the starting fullback and second-team middle linebacker.
"We have just got to make sure that he understands what he is doing on offense," Petrino said. "There is about 15 to 20 percent of the plays in the game in the personnel group that he is in. He just has got to make sure he knows what he is doing because those are real important plays.
"But it is all about what is best for the team," Petrino added. "If they need him more plays over there and we need to move some personnel around, then that is what we will do If they don't, then we will play him as much as we need to."
Petrino says that the offensive line has made a push over the last two weeks.
"I think they have made great improvement in the last 10 days. I think they have really came along. The last two times it has been live tackle they have ran blocked way better. They continue to improve on our pass protection every day. So I am real happy…We have got to go play a game and see how they do, but I have been very happy with them."
The starting offensive line this Saturday will include two walk ons in guard Tyler Deacon and tackle David Hurd.
Both have taken advantage of the opportunity presented before them and pushed pass some scholarship guys.
"They are doing a good job," Petrino said. "They are both tough and it means a lot to them. They have got to be real good technicians and understand what they are doing, but they are two kids that are playing with great effort right now and have just got to continue to do that."
Petrino sad that he has been impressed with what he has seen on film from Jacksonville State senior defensive end Dimetro Tyson (6-2, 275) and junior linebacker Rashad Smith (6-1, 210), the team's leading tackler last season.
"They have a real good end, they have a real good linebacker (Smith) – number 51 that made a lot of plays – and they scored like four touchdowns on defense in one game," Petrino said. "They fly around, they play hard and they've got good athletes. They do a good job."
Petrino made it clear that Arkansas' offense plans to use the whole field - sometimes working underneath and other times going up top.
"I think it will be game-by-game and what the defense is doing," Petrinio said. "I think we have got some big guys that can really move the sticks and I think people will have a hard time stopping them, but we still have enough speed to go down the field….We will still throw the ball down the field a lot, too."
