Kevin Kolb had the final month of his 2011 season wiped out by a concussion, but it's not something that keeps him up at night.
"I don't worry about them," Kolb said, according to the Arizona Cardinals' team site. "It was a freak deal. They don't happen all the time."
Kolb was fitted with a new helmet he believes will protect the back of his head better than the previous model. He doesn't see any reason to get caught up in hypotheticals.
"You can't (be)," he said. "If something comes up, I'll worry about it then. Right now, my head is clear and I know I will be in the league a long time."
Kolb's comments are interesting in that they come at a time when other past and current players are speaking frankly about their concerns over head injuries. Last week, New York Jets linebacker Bart Scott said he earns a living playing football so his son won't have to. Former quarterback and current NFL Network analyst Kurt Warner expressed similar hesitation about allowing his children to play the sport.
Perhaps Kolb -- coming off a disappointing debut season in Arizona and set to enter a competition with John Skelton -- doesn't want to present himself as a liability in any light. He wouldn't be the first NFL player to put competition and job security ahead of long-term health.
