— A lot of talk this offseason has been the arrival of tight end Jared Cook and how he might be a good fit with Rodgers.
It didn’t take long for the quarterback to try and establish some game chemistry as his first two passes went to Cook (he caught the first; the second was a scramble which Rodgers dumped off but fell incomplete).
— Callahan played 51 snaps — 61 percent of the offensive plays.Marquis Williams didn’t enter until the fourth quarter and only got 6 snaps. — Cornerback Kentrell Price played 19 snaps on special teams (70 percent), the most on the team.— Mc Carthy certainly didn’t need to see Mason Crosby attempt field goals.The Packers went for it on fourth down six times — and got a first down on five of those occasions, including a 4th-and-9 from the San Francisco 38-year-line in which Callahan hit Allison for a 10-yard pass.— The Packers were fortunate on the first series of the game.
Quinton Patton got past Sam Shields on a deep pass but Blaine Gabbert overthrew him. The 49ers scored on their next possession, so not the best day for the first-team defense.
— Brandon Burks’ 19-yard touchdown run was the result of good blocking by the Green Bay offensive line and some smart running by Burks.
He made two cutbacks through holes before hitting daylight and making it into the end zone.
After being burned by Chip Kelly’s offense last year in the preseason when Kelly was with Philadelphia, the Packers for the most part held the 49ers in check.
Meanwhile, Aaron Rodgers made his 2016 debut and had the Packers moving at a fast, efficient pace.
— Randall Cobb was flagged for offensive pass interference on Green Bay’s opening drive, wiping out a 48-yard catch-and-run by Adams.
