Kicking a field goal is all about timing. Social media is too, sometimes. About 24 hours after the Bears gave kicker Connor Barth the boot, Robbie Gould, the franchise’s all-time leading kicker who was dumped two years ago in favor of Barth, took to Twitter to conduct a Q&A. The Bears waived Barth Monday morning after he missed a game-tying, 46-yard field goal in a 27-24 loss to the Lions on Sunday. It was Barth’s fifth miss in 16 tries this season. Meanwhile, Gould has made 19-of-21 for the 49ers this season. At first, a fan asked: “When are you coming back to Chicago dude?” Gould coyly replied, “Chicago will be home when I’m finished with my playing career.” Gould just as well could have answered “Dec. 3” when the 49ers visit Soldier Field.
