The Denver Broncos opened up their training camp to record-sized crowds at their Dove Valley facility in suburban Denver yesterday. Over 3,300 fans showed up to the practice, and they were there to see one man, new signal caller Peyton Manning. Manning was greeted by a huge roar as he jogged out to lead the Broncos’ first team offense. Both running back Knowshon Moreno and guard Chris Kuper, who suffered season-ending leg injuries last season, participated in practice yesterday as well.
