Chargers’ pick

ZION JOHNSON, guard 6 foot 3, 312 pounds, Boston College, Round 1, Pick 17 Notable: Johnson spent two years at Davidson before moving on to Boston College, where he played for three seasons. Last season: Johnson returned to college for a super senior season and elevated his draft stock with an impressive showing. Why the Chargers drafted him: The Chargers’ rebuild of their offensive line continues with the addition of Johnson, a versatile piece who slots in as their starter at right guard. They were looking to upgrade the right side of their line after beefing up the left side last offseason. With his addition, the Chargers have Storm Norton and Trey Pipkins left to compete for the starting right tackle spot.
