The Chargers unearthed a gem in undrafted safety Jahleel Addae three years ago and have reaped the benefits ever since.

San Diego's coaches and front office executives have openly called the 26-year old a building block for the future, which is why they placed a second-round tender on the restricted free agent on the first day of free agency.

On Thursday, Addae officially signed his one-year contract.

"The Hitman" is known for routinely delivering bone-rattling hits that bring fans to their feet, making him an intimidating force in the secondary. The 5-10, 195-pound safety ascended into a starting role in 2015, totaling 65 tackles, two tackles for loss, four passes defensed and one sack in 13 games.
