That bridge is burned.  He put himself over his team when he bolted for a bit more money after the Broncos spent years grooming him into a half-decent quarterback.  Plus when he copped an attitude after being benched so that a Hall of Fame quarterback could finish his career with dignity, while, not incidentally, helping win a Superbowl. No coming back for Brock, but he's still a rich SOB, so that should make him pretty happy.
