The Chargers did not attempt a trick play in their first nine games. That doesn’t mean they’re incapable of an occasional sleight-of-hand. Their struggling offense, in fact, has found ways to make a 6-foot-5, 253-pound tight end disappear. Hunter Henry, the second-year pro out of Arkansas and one of the team’s most dangerous weapons, has played a big part in what little success the Chargers’ offense has had. When he has been targeted more than three times, the Chargers are 3-1. When he’s not, they’re 0-5. "I want to get him the ball," coach Anthony Lynn said. "I like it when he's involved, because our offense seems to flow better." The offense purred in a loss to Miami in Week 2, when Philip Rivers completed 31 of 39 passes for 331 yards (seven of them to Henry for 80 yards), and in a loss to Philadelphia in Week 4, when the Chargers racked up 400 yards and Henry made a one-handed, sliding catch in the back of the end zone for a fourth-quarter score. But Henry, who has 24 catches for 319 yards and two touchdowns entering Sunday’s game against the Buffalo Bills, was not targeted once in two of the first three games, a season-opening loss at Denver and a Week 3 loss to Kansas City.
