3 positions where the Cardinals could make a splash in free agency

The Arizona Cardinals could surprise people with moves they make at cornerback, tight end and on the offensive line.

The Arizona Cardinals have a number of needs they need to fill this offseason. They have roughly $12.5 million in salary cap space a week before the league year begins, although they have not made any cap-saving cuts or contract adjustments yet.

Even still, while quarterback Kyler Murray is still on his rookie contract, general manager Steve Keim knows he needs to be aggressive in adding talent to the roster to try and capitalize on the next couple of seasons.

There are three positions in particular where the Cardinals could make a bit of a splash in free agency. Last year, it was the trade for receiver DeAndre Hopkins and then spending money on their defense.

Which positions are they?
