The San Diego Chargers 2014 draft class is officially under contract. First-round pick Jason Verrett signed his deal on Thursday, becoming the final member of the Chargers six-player draft class to sign his contract.

The 25th overall pick signed a four-year deal with a team-option for a fifth year. Exact terms of the deal haven't been disclosed, but under the rookie slotting system, Verrett's fully-guaranteed contract should be worth about $7.89 million, which would include a $4.06 million signing bonus.

Verrett should be able to contribute right away for a Chargers pass defense that ranked 28th overall in the NFL last season.
