The Chargers o-line projects in the bottom seven according to Kent Platte.
Last year, the San Diego Chargers had one of the most injured and least effective offensive lines in football. This offseason, the Chargers addressed that line by re-signing right tackle Joe Barksdale and adding Matt Slauson via free agency after the Chicago Bears released him from his contract.
Many people are actually rather optimistic about the chances of the offensive line bouncing back with a much stronger season than last year's, but at this point in time, all we have to go on is projection and conjecture.
