He sees the finish line of spring practice and he wants to make sure all the coaches and players get the most of it, according to assistant John L. Smith.
"Coach has been on us about trying to push them, too," Smith said. "Each football team every year has a different personality. This team has a totally different personality from last year. He is trying to develop more leadership from within, he is trying to develop more mental toughness by pushing harder, so he is on us as coaches as well.
The Razorbacks will use Saturday's 11th practice of the 15 allotted for another lengthy scrimmage – beginning around 9:45 a.m. - with coaches looking for the same thing as last week.
"It is the same thing over and over each week – better execution, fewer mental mistakes combined with a better effort," Smith said. "…We have to improve, we have to run to the ball. We are not in the habit of everyone going as hard as they can go every play and we have got to develop that. Hopefully execution will be a lot better."
The defense – which got cornerback Darius Winston back on the field Friday - was declared the winner of last Saturday's scrimmage by observers.
"We want to build on what we did last Saturday," Arkansas defensive end Jake Bequette said. "The defense dominated from the get go and we embarrassed the offense. It felt good. We didn't let the offense into the end zone until later in the day."
Petrino got after his offense pretty good after that.
"Coach lashed out at them pretty good," Bequette said. "I've been here three years and that's the first time we've been able to do that…But once isn't enough. We have to be like that on a consistent basis."
Smith said there was still plenty to be displeased about even during the previous Saturday scrimmage.
"We have got to be crisper on our tackles, not as many missed tackles as we had a week ago, we did not particular tackle well so we have to do that better as well," Smith said. "We just have to go out and play better."
One thing that has become noticeable during this week's practices is smallish linebackers Jerico Nelson and Ross Rasner being on the field at the same time.
Smith said both Nelson and Rasner perhaps wouldn't be able to play at the same time against some schemes, there will be times they can.
"They are out there a bunch (together) now," Snith said. "That is one personal grouping that we have that is probably - depending on who we are playing – going to grow. I see that scenario happening because those guys are both playing fast. We know Jerico is really, really good and Ross is becoming a very, very good player."
Senior linebacker Jerry Franklin is being pushed to be more vocal on the field.
"Jerry is studying himself and coming in and taking constructive criticism in the right way and I think he is trying to channel that in the right way and take it to the field," Smith said. "Now is he there yet as far as what we want? No. But he is going to get there and we are going to keep working with him in that regard. He is willing to do that."
Smith said the Razorbacks need to understand that they are not being criticize as an individual.
"We are not criticizing you, we are criticizing your actions," Smith said. "You need to try and make that action better. We are not criticizing you as an individual, but we want better actions and thus better results."
It's clear that mid-term arrivals such as offensive linemen Brey Cook and Jason Peacock, defensive lineman Robert Thomas and linebacker Tyler Gilbert have benefitted from going through spring practice.
"It's going to be amazing for those guys that are here," Smith said. "You take a look at a guy like Brey Cook. How many snaps is he getting this spring? He's getting a whole season. When those other young guys show up to be with him, it is going to be like night and day. He'll be a whole class ahead.
"…In the fall, those kids that are coming in, we are focusing on getting ready for the season and winning games, well, they don't get as much attention and they don't get as many opportunities," Smith continued.
Cook and the other young offensive lineman have caught Bequette's attention.
The defensive line controlled the tempo in that scrimmage, but Bequette sees a young offensive line coming around.
"They've shown great improvement," Bequette said. "And they did some good things in that scrimmage. What happened that day wasn't a reflection on them. I've seen Brey Cook coming on. It's remarkable what he's doing at age 17. Really, the other tackles, Anthony Oden Grant Freeman, are doing well, too. They are getting great reps, over and over. They are coming into their own."
Smith is the special teams coordinator and thus wants improvement in that area.
Punter Dylan Breeding was kicking well on Friday, hitting a 70-yarder on one of his boots.
"We were nowhere near where we wanted to be last year in kickoff returns so we are going to do a bunch more of that as well," Smith said. "And of course punting, we want to see those kids kick. We didn't do a lot of field goals or PATs today, but again we want to make sure (field goal kicker Zach) Hocker is kicking a bunch.
"We haven't worked a lot on the punt return, but we will get to that next week," Smith said. "We have to improve in those areas."
The key in spring when It comes to special teams is getting a lot of kids out there and on film.
"We want to get enough film work done on each aspect that when we come in during the summer and it's all done and we sit down and analyze it, we'll say ‘this guy and this guy and this guy' and that will tell us who's lining up where and who is doing what," Smith said. "That's how you get ahead of the game."
