Arizona Cardinals coach Bruce Arians is sick of people bashing football.

"People that say, 'I won't let my son play [football]' are fools," he told The MMQB in a video interview.

The NFL is embroiled in controversy over the link between degenerative brain diseases like CTE and football. The league's top executive for health and safety, Jeff Miller, recently told Congress this month that there is a link between CTE and football. It was the first time an NFL executive connected the two.

Dallas Cowboys owner Jerry Jones, however, said Tuesday that a link is "absurd." He later amended his remarks to say that the issue needs to be studied further.

Arians appears to subscribe to that viewpoint.

"We have this fear of concussion that is real, but not all of those statistics, I think, can prove anything," he told The MMQB.

Arians had only praise for the game.

"This is the greatest game in the world," Arians said. "I think it teaches more values than any other game that you play. You have things that happen in your life that aren't going to be good. If you play football, you know how to handle them. It doesn't necessarily equate in track and other things."
