The SEC East co-leading No. 10 Gamecocks (7-1, 5-1) will bring the nation's sixth-best defense into its matchup with No. 8 Arkansas (7-1, 4-1) in the SEC's less publicized Top 10 showdown.
That includes some big defensive linemen.
"They have length," McGee said. "They are tall, really playing aggressive and relentless, especially in the passing. And when you are tall like that, you bat a lot of balls down. I think they have a couple of guys that are 6-6 and 6-7 and that is going to be a challenge. We are going to have to find passing lanes and our offensive line is going to have to set at the proper angle and have second effort so it will open up passing lanes for us to throw the ball."
"I think that is true," McGee said. "They are playing different coverages. It seems like they have simplified based on what we played against last year. But I think a lot of times when you simply, it makes you better. The kids start to understand all the details of every coverage and they understand how to match the routes – which is important in playing good pass defense – and you can probably disguise that coverage because you understand all the techniques and angles that go into certain coverages."
With freshman offensive lineman Mitch Smothers injured the last few weeks, Arkansas had gone with a three-tackle rotation featuring senior Grant Freeman, junior Jason Peacock and true freshman Brey Cook.
"It is going to be important for us to keep our quarterback clean," McGee said. "That is the way you pass the ball. Every defense in the country talks about putting pressure on the quarterback, pushing him off his set points and make sure he doesn't get comfortable and pitch off the mound.
"It is going to be important that our offensive line first have initial contact with them, understand their protections and our running backs are part of that protections also," McGee added. "But our receivers and our quarterbacks have to also have the right timing in the passing game. We can't set back there and pat the ball and our receivers have to get down the field like they do. We just have to do it at a high level because it is a big game."
Razorback tight end Chris Gragg said his team is excited about the big match-up.
"It is making us real excited," Gragg said. "We came out today with a lot of energy. We know South Carolina is a good team. It's top 10 match-up right here at home in primetime on ESPN. We are trying to go out here and put on a show for our fans."
Arkansas should have receiver Greg Childs on the field on Saturday after the senior missed last week's game with an injury.
"He looked really good (in practice Tuesday)," McGee said. "I am really excited for him. He understands it is a huge game for us. He has been around here a long time and we talked about the process that this program has been here since we came here and where we are now. I think he understands that and he feels the urgency of this game."
Childs looks as good as he has since his injury late last season in terms of speed according to McGee.
"He is an Arkansas kid and he wants to come out and perform at a high level," McGee said. "He was as fast today as I have seen him. I am really excited to see him get out there this weekend. I think he is going to have a big game."
McGee also noted that senior Dennis Johnson – who has two red zone fumbles in as many weeks – rebounded well in Tuesday's practice.
"He was really good today," McGee said. "We have got mature kids and a lot of them. The guys that have been around and they understand how we are going to go about our business the way the game goes. Dennis had a great practice today. He was fast. He was really intense, concentrating on the details. He understood that that turnover in that game really could have cost us. He understands how important it is to take care of the ball. I am really proud of the way Dennis has grown up the last few years."
There have been a lot of passes thrown to Jarius Wright, Joe Adams and Gragg the last few weeks with no as much distributing the ball around to the other wide receivers.
Asked if that worried him, McGee had a solid answer.
"I like winning," McGee said. "I wish we were moving the ball at a more consistent pace, I wish we were executing and maintaining our drives. I think Cobi Hamilton and Greg Childs are both dynamic athletes. They are going to get the ball more this weekend because of the coverages that they play. We are fortunate that we have a lot of good guys."
Arkansas will not have freshman wide receiver Marquel Wade, who was suspended a game Tuesday by the SEC for his early hit on Vanderbilt punt returner Jonathan Krause on Saturday.
"We have plenty of guys at that position," McGee said. "…But he (Wade) is a really talented player and a tough kid. I know he is really sorry for one – the act that he did to the kid – but also because he is not going to get to help us this weekend. He is down."
