New UA defensive coordinator Paul Haynes laughed about that. He said it isn't much and most may not notice.
"I stayed within the terminology, the lingo, but there were a few things that I saw that we could do different," Haynes said Tuesday when the Hogs went to the Cotton Bowl interviews at the Omni Hotel.
Actually, Haynes said it's just normal stuff that you'd see different in all bowl games if you broke down schemes and technique.
"That's why I say don't get too caught up in putting in something for them. The key is to remain sound. What you have to remember, they've seen everything you can do against their scheme and know the adjustments. So being sound is the key."
Nelson admitted as much.
"That's what impresses you about their quarterback, Collin Klein," Nelson said. "You know every team has game planned something slightly different for him. He's still been productive. It's not like others haven't come up with nice things to stop him. They just adjust to it and go on."
But the Hogs have at least a few things different in their scheme designed for the 6-5, 225-pound running quarterback.
"There are certain little things you key on with him," Nelson said. "There are certain little techniques that we've changed for him. I'm not saying what they are, but you have to do certain things against a quarterback like him."
Could it be that the Hogs have a spy in their defense just for Klein?
"I'm not giving away nothing," defensive end Jake Bequette said. "I'll just say that Coach Haynes has helped us. I've learned a lot from him in a short time. He's helped all of us."
There is one simple key. Make Klein turn the ball over to someone else.
"I think you want their offense going east-west, not north-south," Nelson said. "When he's got it, it's going north-south. So you make him give it. You want him to throw it. You don't want him running it north-south."
That's easier said than done.
"That's like saying the key to the game is to stop them on first and 10," Bequette said. "That's critical. You want to slow them down on first down and put them in lost yardage situations so they have to pass. But not very many have done that against them. That's the same as what everyone tries to do.
"The trick is to get it done. But we know that he's a great north-south guy and we have to stop that first."
The tough part is adjusting to the different aspects of the Kansas State option package.
"They are good enough at it that they could be an option first team, although they do other things," Bequette said. "I am guessing we see plenty of that after he way we played the option against LSU. I'm sure they saw on film that we didn't play it very well. We've been working on it a lot the last four weeks."
Haynes offered some ideas on how to stop an option quarterback. He said they worked against Terrelle Pryor in practice at Ohio State and for the last three years against Denard Robinson, the Michigan quarterback.
"He told us that he had experience against this type of quarterback," safety Tramain Thomas said. "He showed us a few things that helped."
Haynes said Klein is similar to both.
"I'd say he has the body and speed like Terrelle," Haynes said. "Then he has the toughness of Denard. He's like Denard in that he keeps getting better as he goes along. You hit him and he just fights harder. He makes some of his biggest plays in the fourth quarter. He's a great competitor."
Defensive end play will be critical. Both Bequette and Tenarius Wright, the other starter at end, said they will have big roles.
"The option is tough," Wright said. "I played against it a lot in high school and it's never easy. You want to go after the ball, but you have to play assignments.
"I think it's going to be big how both Jake and I play in this game. If we just chase, we won't be very effective. You have to put a certain person on each man and stay man-to-man.
"What you want is to make sure Klein gives it to the back. You eye him down and make him give it up. If it's an option play, tackle him every time."
All true, Haynes said.
"Those two guys, Jake and Tank, are tremendous players," he said. "They have to play huge for us in this game. They have to do a good job of tackling. I can say to have them out there is a treat for me. I like their leadership and what they've brought the last four weeks."
A few months ago, the Hogs went into Cowboys Stadium without them. Both Bequette and Wright were on the sideline with injuries when Texas A&M rolled up 404 total yards on the way to a 35-17 lead. Arkansas rallied for a 42-38 triumph.
"That was frustrating to watch," Wright said. "Our defense was struggling without us."
Freshman Trey Flowers and sophomore Chris Smith had to play almost every down that day.
"But they got it done in the end," Bequette said. "I think that game was the key to our season. Had we lost, we might have ended up just like Texas A&M. Instead, we learned to fight and play to the end."
So what happened at halftime? Were there key adjustments?
"Not really," Nelson said. "Mainly, we decided that we didn't want to play like that. We decided that wasn't us in the first half. We talked more about our offseason commitment and how hard we'd worked to let it go on like that."
Still, it didn't go as planned. Even with a 10-2 season, Bequette said there are things that weren't right.
"The defense wasn't very consistent," he said. "We can make all kinds of excuses -- like the injuries to me and Tank. But the main thing, we didn't play like we wanted to and we want to play better than that Friday night."
Bequette said the seniors also are glad to be at the start of the Paul Haynes era.
"I think we can see that Coach Haynes is bringing something different. I think we also know that there are good young players ready to step in for us older guys and they are going to be good. We'd like for that to get going in this game."
