The San Diego Chargers are coming off an extremely disappointing season, one that was defined by major injuries on both sides of the ball on the field and rumors of relocation off the field. 

While Philip Rivers put up some huge numbers, most of that had to do with an inability of San Diego to run the ball and what has to be considered major injury issues on the offensive line. 

Despite finishing last in the AFC West, there is still a ton of talent here. This is an indication that the Chargers can get back into contenting status with a solid draft and some decent additions in free agency. 

In continuing with this 32 article series, here's a look at the top needs for the San Diego Chargers as well as a seven-round mock draft we ran through the FanSpeak mock draft simulator. We manually picked for San Diego while the picks for all other 31 teams were selected by the simulator. 

1. Offensive Tackle

Injuries along the offensive line impacted the Chargers more than any other team in the NFL. Their opening day starting five missed 40 percent of the team's games. That's absolutely absurd. When looking at the issues here, it's more about pass protection. D.J. Fluker seems best suited for the inside, a position he can absolutely dominate.

Meanwhile, King Dunlap is nowhere near a franchise left tackle. Add in a need at right tackle, one that could be filled with Dunlap moving to that side, and it's readily apparent this is an area of major concern for San Diego. 

2. Cornerback

Brandon Flowers was among the worst regular corners in the NFL this past season. He also doesn't necessarily have much of a future in San Diego. And while Jason Verrett performed at a Pro Bowl level, there isn't much more after him on the depth chart. 

San Diego's front seven might be good, especially from a pass-rush standpoint. But it still needs to have multiple starter-caliber corners. That's only magnified with the departure of Eric Weddle at free safety. Short of this happening, the Chargers are going to have an issue stopping teams through the air. 

3. Wide Receiver

Keenan Allen has proven himself to be a No. 1 wide receiver in the NFL. And despite missing the final eight games of last season, he's earned the trust of both Philip Rivers and the organization.

Outside of that, there isn't much to see here. Malcom Floyd is calling it quits. Stevie Johnson failed to fit in and couldn't stay healthy. Meanwhile, the combination of lesser receivers failed to stand out in 2015. 

Rivers has committed to this team. He's planning on playing the remainder of his career in San Diego (or wherever the Chargers end up), it's high time the organization provides him with an elite-level receiving group. Selecting one in the top of the draft might just do that. 

4. Free Safety

Things may have ended in an ugly manner between Eric Weddle and the Chargers, but he was the face of the team's defense for nine seasons. His departure is going to be huge from both a talent and leadership perspective.

And without another veteran to fill the void, the Chargers' ability to perform at a high level on the defensive side of the ball is going to be impacted. This leads me to believe the team might very well target the only Pro Bowl caliber safety in the 2016 NFL draft (see below).
