Receiver Davante Adams needed just one series to show he was in midseason form for the Green Bay Packers. He had impressive preseason debut as the Packers won their exhibition opener 31-17. Quarterback Aaron Rodgers was one of many Packers starters to sit out. But backup Brett Hundley showed glimpses of improvement under center, going 6 of 8 for 95 yards and an 8-yard score to running back Jamaal Williams on the drive after Tennessee’s score. Hundley also threw an interception. The Packers will host Pittsburgh next Thursday night.
