Time after time, the Razorbacks couldn't punch it in on short and goal.
It is something that Petrus (6-4, 315) - who recently bench pressed a whopping 515 pounds and started 12 games in 2007 - who hopes to help end this season with both his technique and mentality.
"When you get down there on the goal line, it's just about who is going to get it in and who's not," Petrus said. "That's really all it is about – having more willpower and not being a punk about it, just going and being a man and going and getting the job done."
Petrus is currently the starter at strong guard, moving over there from weak guard just a few days ago.
That has the preseason 2008 SEC second-team all-conference selectee, butting heads with standout Arkansas defensive lineman Malcolm Sheppard.
"They moved me to strong guard so that put me on Shep a whole lot more," Petrus said. "It's a battle out there. It ain't no easy job, but I enjoy it because Shep is the best in the business. If I can get him down, I can probably be ready to take on anyone in the SEC."
In all honesty, Petrus is just happy to be back out on the field butting heads after a year of doing some rather odd stuff off of it.
Petrus, who saw action at tight end and fullback earlier in his career, did under the tutelage of UA strength and conditioning coach Jason Veltkamp.
"They put me on a special workout deal - a special plan in the weight room with Coach Veltkamp," Petrus said. "They had me doing like unordinary stuff. There was no need for me to get any stronger so they wanted me to get more explosive and faster.
"I was boxing, sparring with Coach Sharp," Petrus added. "I did that a couple of times a week and I did this jumping thing to get more explosion in my hips. We worked on that all through the season and it really helped me get off against those three techniques and getting movement on these big guys on the d-line, guys like Shep."
The offensive line – working in some new starters - had a very good scrimmage this past Saturday.
"Obviously it feels really good," Petrus said. "We have been moving guys around a little bit. We are working on being more consistent.
"…We have a basis for the offense so we are not really as worried about that," Petrus said. "When we install stuff, we know it so we are don't run around with our heads and don't know what is going on. We anticipate stuff, we recognize defenses better."
That momentum carried over to Tuesday's practice.
"Today we came out and the O-line got after it," Petrus said. "It was a good day for the O-line. That's what we are enjoying. We just want to be consistent every day so we can make progress."
Petrus bench pressed 320 his senior season at Carlisle, 365 by the time he arrived at Arkansas.
That has obviously increased since he made it to Arkansas.
"I did 515 as a max," Petrus said. "I did that a couple of weeks ago…I think Shawn Andrews did 515 so I tied for it. I'm four years into this thing and have worked hard and got it up.
Petrus has tried to take young offensive linemen Grant Freeman and Matt Hall under his wing.
"I talk to both of those guys and try to help them out with certain stuff," Petrus said. "If I see them I say ‘you might want to try and do this, the defensive line is giving this movement right here and you might want do something.'
He also stresses about getting off the ball on the snap.
"If we know what it is on, you definitely don't want to be late," Petrus said. " A lot of them that come in here are nervous and not really sure what to do so they are late off the ball. If you are wrong, your wrong, but make sure you are getting off the ball fast. Anything you can do to help yourself like that gives you a chance.
"They have improved a whole bunch – Matt Hall and Grant," Petrus added. "They are both a lot better. When they first came in, you said ‘boy, they've got a long ways to go.' But they are getting there and they are showing a lot of improvement."
Getting back to the goal line play, Petrus thinks having a big back like Broderick Green or incoming freshmen Ronnie Wingo will help. "That was really disturbing last year and hopefully if Broderick Green can get in we can have a chance for him," Petrus said. "If he gets cleared and has a chance to play, he can really help us on the goal line.
"Mike Smith just gets so beat up down there," Petrus said of the starter." He runs the whole series and then he gets down there. We can't use somebody little if they are know we are going to run right up the middle. We need somebody with a little more weight who is fresh.
"Mike does a great job, but if we can get somebody like that and the offensive line can get a little bit more mean streak, than we can get it done," Petrus said.
