The Westbrook standout made the decision to accept the scholarship offer from Mississippi State after his official visit to Starkille this past weekend.
"I liked the winning tradition that they have," said Shane. "It's a great atmosphere and a great campus. Coach Croom is a great person and he knows a lot about football. He's really building a great program."
Westbrook High School head football coach Craig Stump once served as an assistant coach at Mississippi State, so he was able to answer many of Shane's questions.
"He told me that it was a nice University," said Shane. "He said that no matter where I go I was going to get a good education."
Earlier today Shane had to deliver the news to the Baylor coaching staff. It was not a matter he took lightly.
"It was kind of difficult because I didn't really know how to tell them," said McCardell. "It was real hard because I had such a relationship with them."
Shane said the chance to win early in his career was possible at MSU.
"It was a hard decision to make, but I decided on Mississippi State because they just got out of a bowl game and they are not really losing many seniors. They will continue to win," said McCardell.
The 6-4, 219 pounder reports a 4.5 40 yard dash and a 39 inch vertical leap. He believes these attributes give him an advantage off the edge.
"I think I am good at rushing the quarterback," said Shane. "I think I have enough speed to get around the offensive tackles with ease. I think my quickness off the ball really gives me an advantage."
McCardell got the chance to take the guided tour of the Bulldog football facilities and he was pleased with what he saw.
"It was great," said Shane. "I got to see the indoor facility and I loved it. The coaches told me that we would practice in there the majority of the time when we had bad weather and things like that.
I got to see the basketball arena. They played Ole Miss and they beat them. I got to see the recreational center and all of the dorms. I was really impressed with all of it."
Another member of the McCardell family was also impressed with all things Bulldog.
"First of all we liked the University," said Shane's father Nathaniel. "After meeting with Coach Croom and his coaching staff we felt like they were the best in the country. Those guys have turned that program around. It's not so much about the bricks and mortar. It's about the people and in the end that's what it boiled down to. Shane and I both really liked the coaches and the players just seemed to really have that camaraderie. It just all came together and I think it was a great experience."
Before Shane went public with his decision he wanted to sit down and talk to his mother. After a good night's sleep, McCardell his move.
"We called her and told her that he really liked it over there," said Nathaniel. "We didn't really talk about it until we got back yesterday. This morning he just went on and made his final decision. His mother is one of those that is going to be happy if he is happy. She is behind him 100%."
The Bulldogs made their offer to Shane early last week, but it appears he had been on the MSU radar for some time.
"They came and looked at him back during the spring of his junior year," said Nathaniel. "They liked him then, but I guess they needed a defensive end and came back. Talking to the coaches, they had him the whole time. They were over in Mississippi and finally got the chance to come back over and get with him. We are all really excited about how things turned out."
McCardell chose the Bulldogs over offers from Arkansas, Baylor, Boise State, North Texas, Tulane and Texas State.
Shane marks the Bulldogs 24th public commitment towards the 2008 signing class.
