The San Diego Chargers haven’t made a big splash in free agency. But they have made a series of relatively small splashes.

The latest comes from a trio of signings that the team announced on Monday. Joining the roster are receiver Deon Butler, receiver Dan DePalma, and cornerback Cornelius Brown.

The biggest name by far is Butler, a third-round pick of the Seahawks in 2009. He spent all four NFL seasons in Seattle.

DePalma has spent time during the past two seasons on the Giants’ practice squad, and Brown has spent time with the Bears and Colts.
