Bolts quiet on opening day of free agency

While several teams made noise during the opening hours of NFL free agency Tuesday, the San Diego Chargers predictably stood pat.

ESPN's John Clayton reported that 26 unrestricted free agents moved to different teams in the first 90 minutes of free agency, but the Chargers were not involved in any of that movement.

San Diego did show interest in Houston Texans free-agent defensive tackle Earl Mitchell. However, the University of Arizona product made a trip to Miami, where he ultimately agreed to a four-year, $16 million deal that includes $9 million in guaranteed money.

Part of the reason for San Diego's lack of involvement in the opening of free agency is the team has limited salary cap space, so the Chargers don't have much cap room to spend lavishly.

Further, Chargers general manager Tom Telesco's mantra is to build through the draft.

The Chargers could make a deal soon. First reported by Aaron Wilson of the Baltimore Sun, Indianapolis Colts free agent inside linebacker Kavell Conner is scheduled to visit Wednesday with the Chargers.

Conner, 27, totaled a career-high 104 tackles in 15 starts with Indianapolis in 2011. Telesco worked in the Colts' personnel department when the team drafted Conner out of Clemson in the seventh round in 2010. At 6-foot and 240 pounds, Conner would likely compete for a roster spot as a reserve inside linebacker behind Donald Butler and Manti Te'o.
