Named as a second team preseason All-ACC selection and one of the proven leaders of this team, Walker believes that this year's team has the right mindset going into Saturday.
"The attitude of this team is totally different from last year," he told CUTigers. "Guys are buying in and it's been really exciting for me to see that. There is a difference this year in taking game week seriously and being focused in practice."
Walker also confirmed what has been written most of the offseason and preseason camp - there is a different feeling about this team compared to a year ago.
And most of it has do with an area he's very familiar with - leadership.
"Our senior core year this is very experienced," he said. "That's where leadership comes from- guys that have been there before. We've got a lot of that, especially on the front lines. We've got everybody on the same page, and we're showing the young guys what they need to be doing."
Walker will face a tough test in week one going up against Troy defensive end Jonathan Massaquoi. Named to the 2011 Bednarik Watch List, an award given to the nation's top defensive lineman, Massaquoi led his team in sacks last year with 13.5.
The standout defender was a popular topic of conversation during Tuesday's press conference.
"Massaquoi is a great player," he said. "To me, he's a mix between Andre Branch and Kortnei Brown. He likes to catch you leaning in off your line and swap your hands away.
"But it's nothing I've never seen before. I'll be ready for it. I've been competing against Malliciah Goodman all summer. I don't think I'll face another defensive end that's better than Malliciah."
One area where Dabo Swinney has expressed concern is the Tigers' depth on both sides of the ball. Walker addressed that issue Tuesday by talking about Clemson's utility man- Mason Cloy.
"Our sixth man on the line is Mason Cloy," he said. "He had a great spring and knows this is our last go-around as seniors. To be honest with you, I probably wouldn't even notice if Mason stepped in the game. There would be no drop off in play." (Roy Philpott)

Running a fast pace offense, new offensive coordinator Chad Morris will look to run as many plays as possible. Games are won and lost in the trenches, and Walker knows the starting five for the offensive line will carry a large load.
"In years past, the guys on the line shared more reps," he said. "That won't be the case this year. We don't expect a drop off if different guys come in, but I expect to play the whole time.
"Whether it's a three and out by our defense, or first downs by our offense, we are going to be on the field a lot. But that's we've been working on all camp. We'll be ready."
