Carradine showed up on FSU's camp as a junior college star from Butler C.C. in Kansas. But because of the Seminoles depth at his position he was a backup and a very talented one at that. Then the start got injured.
"I came from JC [junior college] and they already had a bunch of guys as good as me," Carradine said. "So I had to learn and I was a backup. Then [Brandon] Jenkins went down."
Jenkins broke his foot in the first quarter of the first game of the season. Carradine, 6-foot-4 and 276-pounds, picked it up quickly and had a good season finishing with 11 sacks.
"It was a different year," Carradine said. "Brandon got hurt and I adjusted. I played the season and was ready to go. It was one of those things where I got better with every practice."
During the regular season finale against rival Florida, Carradine blew out his knee. His 2012 season was terrific and many considered him a potential first round pick. Now he's battling rehab.
"It's been two months and three weeks," Carradine said. "I start running on the [February] 26th. I have been working out five days a week twice a day in Houston. I will be 100% by April and hope to do this same combine stuff for everyone before the draft. I really don't pay attention about where I will be drafted right now. I had the injury and just have to keep working out."
Carradine is embracing the rehab which he says is reminiscent of the type of person and player that he is.
"I am a great person and I have a passion for football," Carradine said. "I am a player loves to win. I have a good motor and am physical. I can run and be disruptive all over the field. I am an impact guy all over the field.
"But I have to get better. I want to improve my technique and speed off the ball. I want to get quicker off the ball."
