(SportsNetwork.com) - Not a lot of people have noticed but the Arizona Cardinals have quickly turned into one of the more talented teams in all of football.

Perhaps the best club not to make the playoffs in 2013, the Cards are hoping to tweak the roster a bit to get over the hump under second-year coach Bruce Arians.

Their biggest weakness -- the offensive line -- was addressed in free agency when the team brought former Raider Jared Veldheer in to play left tackle. That move, along with the return of immensely talented guard Jonathan Cooper (last year's first-round pick) from a broken left fibula should solidify things in front of quarterback Carson Palmer, who will turn 35 late next season.

Palmer helped Arizona double its win total from 2012 but at his age, it's prudent that the Cardinals start thinking about the heir apparent.

Other areas of need include safety and running back. In the defensive backfield, 2013 rookie Tyrann Mathieu proved to be a playmaker but tore both his ACL and LCL in a victory over the St. Louis Rams in December. Meanwhile, fellow freshman Andre Ellington proved to be a big-play threat in his inaugural NFL campaign but may not have the size and physicality to be an every down bell cow at running back.

Top Needs: S, RB, QB, TE
