The San Diego Chargers did not address their top need in the NFL draft, so it makes sense that they ramp up their pursuit of free agent left tackle Bryant McKinnie.

CBS Sports reports that the Chargers have a visit with McKinnie, a starter on Super Bowl champion Baltimore. He is also visiting Miami.

As of now, King Dunlap would be the Chargers' left tackle, but he is not considered a solid NFL starter. But if the Chargers don’t sign McKinnie, they may have to use Dunlap as Philip Rivers’ blindside protector.

Miami’s interest in McKinnie doesn’t only impact San Diego. If the Dolphins sign McKinnie, it would officially end any chance of Miami trading for Kansas City left tackle Branden Albert.

Update: Perhaps the Chargers will show interest in Adam Synder, who was cut by the Cardinals. Synder is a solid backup at all five positions. He played for new San Diego offensive coordinator Ken Whisenhunt last year.
