Bruce Arians says the Arizona Cardinals have no concerns about overusing David Johnson.

"He's still too young to overuse," Arians said of his running back.

"I want to have 30 touches out of him, if possible, because that's going to be a lot of offense," the coach added. "When he has his hand on the ball, either as a wide receiver, coming out of the backfield, in the slot, and running, that's a lot of potential offense for us."

Johnson had 293 carries and 80 catches in 2016, totaling 2,118 yards and 20 touchdowns.
