The Arizona Cardinals moved forward in a new direction at quarterback this offseason by bringing aboard Sam Bradford on a one-year, $20 million deal via NFL free agency.

However, there remain lingering questions concerning the health of knees having suffered a pair of tears to his left ACL. According to Darren Urban of azcardinals.com, Bradford voiced uncertainty if he will be able to play in all 16 regular season games this upcoming campaign.

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.”

Bradford has seen his career marred by injuries that have limited his availability as he hasn't played an entire season since the 2012 season with the then-St. Louis Rams. The 30-year-old is also coming off a season where made just a pair of appearances as he was dealing with nagging issues to his left knee.

This has fairly raised the question of whether he can stay healthy throughout the duration of the season. The Cardinals have a lot riding on Bradford's shoulders to be a major factor in their offensive game plan in 2018. He will have a couple of Pro Bowl talents in wide receiver Larry Fitzgerald and running back David Johnson around him.

There will remain a large amount of focus on whether Bradford's knees will allow him to get through a whole season without any lingering issues. For the time being, the Cardinals will have to continue to address questions about the health of their starting quarterback.
