Amazing what one year with great coaches can make for someone.

Prior to this season, many questioned whether Phillip Rivers had his best days behind him or not.  However, with the additions of wide receiver Keenan Allen, head coach Mike McCoy, and offensive coordinator Ken Wizenhunt, Phillip Rivers had one of his best years as a pro this past season.

However, while making it to the playoffs is great, the Chargers have a long way to go with this defense to go even farther in the future.

1. Cornerback

This team's pass defense was really bad last season.  They couldn't stop anyone outside of a few games against divisional opponents.

Also, playing against Peyton Manning twice a year isn't fun so corners are a necessity if this talented team ever wants to finally help Phillip Rivers get to a Super Bowl.

One corner that may be available at 25 overally is Kyle Fuller out of Virginia who would be a nice addition to a very underachieving secondary outside of safety Eric Weddle.

2. Outside Linebacker

After losing Shaun Phillips to the Denver Broncos last season, the San Diego Chargers thought that Dwight Freeney would fill the hole left by Phillips in their 3-4 defense.  Well, they were wrong.

Not only is Freeney on the wrong side of 30, but wasn't very good before going on IR in October.  They need another pass rusher to help this defense out opposite of Melvin Ingram.

A few guys that could provide an upgrade could be Dee Ford out of Auburn, who could transition to a 3-4 and is one of the most underrated pass rushers in this class, or even someone such as Kony Ealy out of Missouri.

3. Nose Tackle

Nose tackle isn't the biggest need for this defense and it's relatively easy to find a servicable one in the later rounds.  However, it's relevant because if the Chargers don't like any of the corners or outside linebackers on the board, they could decide to go with Louis Nix out of Notre Dame to plug up the middle.

What I Would Do

I've said it before and I'll say it again; this is the year to need a cornerback or a wide receiver. 

Both positions are so extremely deep this season that you can potentially find a solid starter in the third round this year.  With that being said, if Dee Ford is available jump all over him to form a nice pass rushing tandem with Melvin Ingram.
