The Arizona Cardinals made a calculated risk this offseason by signing quarterback Sam Bradford to be their new starting quarterback. Bradford, who has a history of knee problems, missed virtually all of last season due to a recurrence of that knee issue.

Bradford is still working his way back from that significant setback. So despite having a new system to learn under a new coaching staff, Cardinals head coach Steve Wilks says the team will exercise patience and caution in terms of getting Bradford on the field to work on the new offense this offseason.

“The biggest thing we’re going to do with Sam is make sure that he’s ready to play 16-plus games,” Wilks said per Pro Football Talk’s Josh Alper. “I’ve seen what he can do over the years. I’m not concerned about trying to get him out there quick as possible to throw the ball.”

It makes all the sense in the world for Wilks and the Cardinals to take that approach with Bradford. Given his extensive history of knee problems, the Cardinals need to take every possible precaution to ensure Bradford will be healthy and ready to go for the start of the season.

Of course, there’s still the risk that Bradford goes down with another injury anyway even with limited work in the offseason. If he does, the Cardinals have the likes of Mike Glennon, Brandon Doughty, and Alex Torgersen as possible backups.

But the Cardinals knew what they were getting themselves into when they signed an injury-prone quarterback in Bradford, and they’ll just have to make the most of it.
