After locking up their top draft pick, first-round wide receiver Mike Williams, earlier Thursday, the Chargers went to work on signing a few other selections, per Eric D. Williams of ESPN.com. The club inked four more rookies to deals, including second-round pick and former Western Kentucky guard Forrest Lamp. Here are the others:

• Round 5 (No. 151 overall) Desmond King, DB (Iowa)
• Round 6 (No. 190) Sam Tevi, T (Utah)
• Round 7 (No. 225): Isaac Rochell, DT (Notre Dame)

Lamp drew plenty of first-round buzz entering the draft, but the team that seemed to like him more than anyone else, Miami, cooled on him at the 11th hour. The Chargers ended up selecting Lamp 38th overall, and he could be an immediate factor – perhaps at right guard – on a line that Football Outsiders ranked among the NFL’s worst last season.

With Lamp, King, Tevi and Rochell now under contract, only two of the Chargers’ seven picks are without deals.
