While things can change, the odds are the San Diego Chargers will head to the 2013 season with King Dunlap as their left tackle.

He was signed early in free agency, presumably to provide depth at both tackle spots. But because the Chargers have been unable to address their most glaring hole, Dunlap, who was with the Eagles, is first in line to get the chance to protect Philip Rivers' blindside.

The other options are using Mike Harris or Kevin Haslam. Both players started multiple games last season, but neither appears to be strong options. The free-agent market is very thin at this point.

“It’s not a good situation,” ESPN's Matt Williamson said. “I would say it is the worst left tackle situation in the NFL ... I would go with Dunlap of those terrible options.”

Williamson said Dunlap did not play too poorly last year, but he also thinks Dunlap is best suited for right tackle. That is not an option in San Diego with the team taking D.J. Fluker with the No. 11 overall pick.

“He has great size, but he is heavy-footed and can really struggle to play low enough due to his extreme height,” Williamson said of the 6-foot-9, 330-pound Dunlap. “At best, he is a right tackle athlete and not suited to playing on the left side. But he actually didn’t play as terrible last year as many assume ... With his size and long arms, he can be one of those OTs that take an extra step to get around in protection -- that might be his greatest asset.”

At this point, the Chargers will take any positive involving a tough situation.
