The Arizona Cardinals were busy during the first wave of NFL free agency. They added six new players and brought back a couple, addressing some key areas of need. They addressed the interior of the offensive line, inside linebacker and the defensive line.

Th first wave is more than likely about over. Now teams will start finding bargains and players with more question marks.

What do the Cardinals need to do next in free agency? Where do they still need to add players?

Outside linebacker:

The team really wanted to improve in the pass rush. They targeted Brian Orakpo, but lost out on him when he signed for pretty big money with the Titans. They added LaMarr Woodley, but no one should expect a big contribution. What he adds is a good veteran presence.

The problem is there is not much left on the market.

Maybe someone will stand out or get cut.

Running back:

Arizona wants to add a bigger back, one to complement Andre Ellington and to handle short yardage situations. There is a bit of a waiting game, as the team is rumored to be interested in trading for Adrian Peterson and that would take care of the situation.

Until there is a resolution there, the Cardinals have a dual need at the position -- a veteran presence and a big back. Peterson could take care of both.

Arizona still could draft someone, but expect a veteran be added at some point.

Kick and punt returner:

The Cardinals don't really have anyone on the roster who is a proven returner, except Patrick Peterson, and Peterson hasn't been good at punt returns since his rookie season.

They could turn to John Brown, but at some point, it would make sense to bring a guy to compete for the job.

Cornerback:

This isn't a dire need, but it is a position where another veteran could be nice. It isn't going to be a big name, but it could be a signing line adding Antoine Cason a couple of years ago, someone to add some more leadership and competition.

...

Arizona might not add someone in each area and, aside from maybe a trade for Peterson, there isn't likely going to be any "name" players, but these would be the areas to watch for with possible secondary moves in free agency.
