Colledge's addition and Cards' OL planning

The Arizona Cardinals are reaching into free agency to patch holes on their offensive line.

Daryn Colledge, a starter for each of his five seasons since Green Bay made him a second-round choice in 2006, gives the team needed reinforcement at guard. Alan Faneca's retirement and Deuce Lutui's potential departure in free agency combined with the Cardinals' draft-day tendencies to compel such a move.

Colledge, posting on his Twitter account, said he would be in camp with Arizona soon. ESPN's John Clayton reports terms as five years and $27.5 million.

The 29-year-old starter of 76 regular-season games ideally would have remained with Green Bay. In this case, the Packers did what they have often tried to do: identify starting-caliber talent in the draft, secure the player for his prime years at a reasonable rate and then watch another team sign that player at a premium price in free agency years later. General manager Ted Thompson touched upon that theme during his meeting with shareholders Thursday.

Arizona has also taken pride in developing draft choices into starters -- Calais Campbell successfully replaced free-agent departure Antonio Smith, to cite one example -- but the team hasn't invested significant draft capital in its offensive line since making tackle Levi Brown the fifth overall choice in 2007.
