Today is a special day on the Chicago Bears 2015 calendar because it’s the day that all players, rookies and veterans alike, report to Training Camp at Olivet Nazarene University in Bourbonnais. While that fact grabs the headlines for Bears fans, today also happens to be 46 days away from the regular season opener. We’ve been counting down the days here at Bear Goggles On in our Countdown to Kickoff series, and today we’ll rip another sheet off of that desk calendar. In the spotlight on this day is an undrafted rookie safety out of UCLA who is largely unknown to Bears fans, #46 Anthony Jefferson.
