The Cardinals' most notable wide receiver addition to this point was the free agent signing of former No. 7 overall pick Kevin White to a one-year deal. White has not lived up to expectations in the NFL, in large part due to injuries, and the Cardinals are looking for a way to unlock his potential.

"That's what we're trying to find out," Kingsbury said. "Taking to guys that have been around him in Chicago -- and I know his college coaches really, really well -- they rave about his toughness, personality, competitive spirit, so I think just a fresh start (helps). He had some tough injuries. He's still 6-3, 205 and ran a 4.3 at the combine. And so, we got to try and see what he's got because I watched it in person on the sideline and he can be a dangerous player, and we're hoping that that's what we get."

David Johnson's lack of production in the passing game was a big storyline a season ago and Kingsbury is expected to remedy that issue. Kingsbury is excited about Johnson's special skillset.

"He's a big back and when you split him out and put him in space like that he looks like a true receiver, so that's a unique combination," Kingsbury said. "You get a linebacker on him, you should feel comfortable he's going to win that one."

Atop Kingsbury's wish list was a speedster to take the top off a defense. The Cardinals added a candidate to do that just hours after Kingsbury spoke when Damiere Byrd was inked to a one-year deal. Byrd reportedly ran a 4.28 40-yard dash at his Pro Day in 2015.
