It's just the preseason, but the way Tyson Bagent and Case Keenum played Sunday had to make Johnson feel good about his QB depth chart.

According to Bears reporter Larry Mayer, three Bears players in particular, Ozzy Trapilo, Dominique Robinson and Nahshon Wright, will be under the microscope as they battle for starting spots.

Johnson isn’t playing most of his starters Sunday, but the Bears' first preseason game against the Dolphins is an important dry run for at least one person — Johnson himself.
