Chargers’ Quentin Johnston finds comfort zone after rocky rookie season

EL SEGUNDO — Quentin Johnston sprinted toward the corner of the end zone, looking relaxed and confident as he ran his route the other day during a training camp drill. He boxed out a defender, as a basketball player might jostle for a rebound beneath the basket. Then he leaped and caught the pass.

One day later, he ran a different route along the sideline, making sharp moves to shed himself off a defender. He turned to find the pass wasn’t as precise as it could have been. He slowed and adjusted his body so he could make the catch.
