Chargers add O-line depth

The San Diego Chargers added depth to their offensive line with the experienced Rex Hadnot.

Hadnot is an eight-year veteran and started all 16 games for the Arizona Cardinals last season. He is insurance if the Chargers are not comfortable with Tyronne Green at left guard who is replacing the retired Kris Dielman.

The Chargers were ravaged by injuries on the offensive line last season, so having a player like Hadnot is important.

The Chargers also announced their undrafted rookie class. Here is the list:

UPDATE: The Chargers expect fifth-round draft pick Johnnie Troutman to miss the entire season because of a torn pectoral muscle he injured two weeks ago. The Chargers knew of Troutman’s injury when they drafted him. But the team loves his long-term potential.
