Cardinals beefing up their line

The Cardinals beefed up their depth on the offensive line with two moves Thursday.

They re-signed Jeremy Bridges, who played well when needed at left tackle last season, before adding veteran guard Rex Hadnot, an unrestricted free agent from the Browns. ESPN's John Clayton is reporting Hadnot's agreement.

These look like smart moves for Arizona. Hadnot weighs 320 pounds and has started every year since entering the NFL in 2004. A knee injury sidelined him for part of last season.

The Cardinals tendered right guard Deuce Lutui to a second-round choice. Lutui remains unsigned, but he played well last season and projects as a likely starter in 2010. Hadnot could provide valuable depth for all three interior positions, giving the Cardinals additional flexibility as they consider options in the draft. Left guard Reggie Wells is scheduled to earn $2.4 million in 2010, the final year of his deal. Wells has been a good player for Arizona, but 2009 was not his best season.

Re-signing Bridges, who can play guard or tackle, and adding Hadnot, strictly an interior lineman, improves the Cardinals' depth. The team arguably could use another tackle and preferably one skilled in pass protection.

The Scouts Inc. report on Hadnot heading into last season reads:

Hadnot was the Browns' starting right guard in 2008 and has demonstrated the ability to play any of the three interior offensive line positions. He is a powerful, wide-bodied blocker, but isn't particularly quick or agile. Once beaten, he is slow to recover and his overall agility is just average, but he does show the ability to engulf his opponent at times. Ideally, he is a swing interior backup.
