Bad Rex was back at his worst Monday night. Not that the Bears needed any reminders of what happens when Grossman goes awry -- even in the preseason. After struggling for most of Grossman's 26 plays, the Bears' backups bailed him out and eventually overcame the miscues to beat the Colts 27-24. "I haven't lost any (confidence)," Grossman said. "I hope the Chicago fans and everyone else hasn't lost any. I'm a pretty optimistic guy. Just because I throw an interception in the preseason doesn't take away from a good camp."
