Maybe it was just a fist bump. Maybe it didn’t mean anything. But maybe it was a sign that, for the first time in his Bears career, Jay Cutler will have a head coach who can pick him — and the rest of the team — up when things aren’t going well. Maybe it was a sign that the Bears have a coach who understands the ups and downs that happen on game day and knows how to react to them. Maybe it was evidence that Cutler finally has a coach who can bring the best out of him.
