The San Diego Chargers are in the midst of a very difficult time as an organization.
The team is accused of having used the illegal substance "Stickum" during their loss to the Denver Broncos.
The loss to the Broncos was one of the most disheartening losses in the franchise's history. This is especially significant because the Chargers have a long history of disappointing losses.
Since the past few weeks have been so disappointing for the Chargers, let's briefly forget about the recent event and take a look at how the team can improve during the offseason.
The San Diego Chargers are in dire need of an offensive tackle.
Jared Gaither cannot stay healthy, and Jeromey Clary is one of the worst starting tackles in the NFL.
A number of impressive tackles are slated to become free agents in 2013.
Jake Long, Duane Brown, Sebastian Vollmer, Ryan Clady, Jermon Bushrod, Will Svitek and Andre Smith all face free agency.
Long, Brown, Vollmer and Clady are likely out of the Chargers' price range, but there's no doubt that the rest of the list would be a huge upgrade over Clary at right tackle.
In the offseason, both Quentin Jammer and Antoine Cason spoke of making huge improvements after the two performed poorly in 2011.
They have clearly not followed through on their promises.
The Chargers have found that Jammer still bites on double moves, and Cason looks like he should be a nickelback.
Both players will be free agents after the 2012 season, and it might be smart for the Chargers to allow both of them to find new teams.
The Chargers should look to take a cornerback early in the 2013 draft to fill one spot. To fill the other cornerback position, the team should bring in a free agent.
Jason McCourty and Sam Shields are two young cornerbacks who have looked much better than Antoine Cason.
The team could also bring in veteran Marcus Trufant on a short contract. Trufant is a solid player, but he lost his starting position to Richard Sherman—one of the most impressive young players in the NFL.
Tyronne Green has been a huge disappointment in his first year as a full-time starter.
For the Chargers to improve their running game, they need to replace Green.
The Buffalo Bills have three good guards who will be free agents after 2012.
Andy Levitre is their best guard, but they will likely throw a ton of money his way to retain him.
Kraig Urbik and Chad Rinehart wouldn't require as much money as Levitre, but they are both restricted free agents.
In addition to the three Bills linemen, Brandon Moore of the New York Jets would be a great replacement for Green.
