The San Diego Chargers' roster is far from perfect, as is the case with just about every other team gearing up for the 2015 season, but a select few positional units stand out as being either the best or worst.
Each positional unit on the current roster has been dissected and analyzed to distinguish which of these ranks as the best and worst on the team, and for the purposes of keeping things brief, I've narrowed it down to the best two and worst two. Overall ability of the group, along with age and experience, factored into the decision-making process, but so was how they stacked up against the entire roster.
