Chargers’ J.C. Jackson isn’t dwelling on miscues in opener, looking forward to facing Titans

COSTA MESA, Calif. — J.C. Jackson is taking the same approach that Bill Belichick, his former coach in New England, did after a disastrous week.

Jackson was guarded throughout training camp when asked if he would be ready for Week 1. When he wasn’t listed on the practice report leading up to last week’s game, that was the most significant indication he was ready to go.

While there were some signs that Jackson could begin to return to the form he showed during his first four years in New England, there were other moments that resembled last year. Jackson signed a five-year, $82.5 million contract as one of the Chargers’ top free-agent pickups, then had a rough season.

Jackson played 44 of 67 snaps in the 36-34 loss to the Dolphins. He was targeted eight times and allowed three receptions. He also broke up two passes and had his first interception in nearly two years.

The negatives outweighed what would have been a solid return.

The catches Jackson allowed went for 98 yards, including a 35-yard touchdown pass to Tyreek Hill after Hill got separation from Jackson a couple of yards past the line of scrimmage.

Jackson also committed a costly 30-yard pass interference penalty, leading to Miami’s field goal that gave it a 20-17 lead at halftime.

“That was a bad mistake by me, and I take full blame for…
