The San Diego Chargers invested in running back with their first overall pick, but went defense with their final four picks.

The Chargers are looking for more speed on that side of the ball.

“The most important thing and our No. 1 goal this offseason is playing faster,” Chargers defensive coordinator John Pagano said this week. “If we’re thinking too much, we’re not going to play fast. So, our mentality going into this spring is we don’t want thinkers. We want reactors and guys playing fast.”

Second-round selection, linebacker Denzel Perryman, third-round pick, cornerback Craig Mager, fifth-round selection, edge-rusher Kyle Emanuel, and sixth-rounder Darius Philon, a defensive tackle, all ran 40-yard times under five seconds.
