With free agency and the draft in the rearview mirror and training camp just a couple of months away, we assess the San Diego Chargers’ offseason moves.

Best move: Some NFL analysts panned San Diego's signing of running back Donald Brown to a three-year, $10.4 million deal in free agency. Critics surmised that San Diego had more pressing needs on defense and the Chargers could get a cheaper alternative through the draft. But by signing Brown, Chargers general manager Tom Telesco locked up a known entity that will lessen the load for workhorse Ryan Mathews, particularly if San Diego advances deep in the playoffs for a second straight season.

Brown also protects the Chargers should Mathews or Danny Woodhead not come back after the 2014 season. Both are set to hit free agency in 2015. Finally, with as much as head coach Mike McCoy likes to run the ball, the Chargers cannot have too much depth at running back and actually drafted Marion Grice in the sixth round to further bolster that group.

Riskiest move: There is no doubt cornerback Jason Verrett has the skills and mentality to be an effective cover cornerback in the NFL. Still, drafting a smaller cornerback when the trend is to use bigger players on the perimeter is a risky proposition for the Chargers. That Verrett is coming off shoulder surgery to repair a torn labrum and will not be ready to practice until August could leave San Diego looking at a slow transition for the TCU product. That is not good news for a defense that needs immediate help in the secondary.

Most surprising move: Perhaps the most surprising move is one San Diego chose not to make by passing on bringing in a big-name receiver in free agency and waiting until the seventh round to select Baylor speedster Tevin Reese. Receiver was considered a need position for the Chargers heading into this offseason. But as a seventh-round pick, Reese is not guaranteed to make the final roster. So perhaps the Chargers believe Vincent Brown will finally play up to his potential in 2014 and Malcom Floyd can return healthy from a serious neck injury that cut short his 2013 season. The Chargers need a consistent deep threat to emerge opposite second-year pro Keenan Allen.

Double-digit sack guy needed: Corey Liuget led the Chargers in sacks for the second year in a row with 5.5 in 2013. That can’t happen again in 2014. Someone from among a group of edge-rushers that includes Dwight Freeney, Melvin Ingram and Jeremiah Attaochu must emerge as double-digit sack guy for this team to generate a more consistent pass rush and help a young secondary.
