Cardinals quarterback Sam Bradford throws a pass during Thursday's minicamp practice.

When you have multiple serious injuries to the same knee, your offseason work will be affected, and this Sam Bradford knows well.

The quarterback was limited in his first minicamp with the Cardinals this week – the voluntary work wrapped up Thursday – and both he and coach Steve Wilks emphasized it was the only path to take.

"If you just look at what I have gone through, you would be foolish not to have a plan," Bradford said. "The past couple of offseasons, even going into last offseason healthy, there was a plan with what I did."

The plan still allowed Bradford and his repaired left knee to do a lot of what all the other quarterbacks were doing during a minicamp that, while up-tempo, wasn't as intense as what will come later in the offseason once the players have a better

handle on the playbook.

Wilks wasn't concerned after watching his top signal-caller for three days.

"I didn't see anything (bad) out of his knee. Not one thing," Wilks said. "I don't think it's a process of something is wrong with his knee. It's myself and the trainer and everyone else want to go through a process of not getting him out there too soon.

"Nothing is wrong with his knee. I thought he threw the ball well, ball handling, he handed the ball off, rolled out, bootleg, all those things. He's doing everything we ask him to do. We just want to make sure we don't put too much on him too soon."

Bradford was only wearing a sleeve on the knee Wednesday, after wearing a brace earlier in the week.

In less than a month, Bradford said he's already learned new things about his body and his knee, through the "different" training regimen put forth by strength and conditioning coach Buddy Morris. Since Bradford signed, whether it was himself or Morris or Wilks, the emphasis has been for Bradford's availability in October and November more than April and May.  

"You understand you really lay the groundwork for that starting now," Bradford said. "You have to be patient and trust the plan."

Bradford has still been in the meetings, starting up his relationship with offensive coordinator Mike McCoy. Bradford reiterated McCoy doesn't seem wed yet to any one particular offense, waiting to see what the personnel might work the best within.

With this offensive playbook "probably seven or eight" for Bradford in a career marked by different coaches, he is unfazed by having to learn a new system.

He just wants to have a chance to play within it. He was asked if he will reach a point where he will be confident he will play 16 games.

"I don't think you ever know that. No one knows that," Bradford said. "You can feel a great as you can and one play can take that away from you. But I feel with what I have done ... I feel it gives me the best chance to succeed."
