Three NFL teams filled their head Coaching vacancies Wednesday and Thursday.  The Philadelphia Eagles made the biggest splash with the hiring of Chip Kelly of Oregon as their new head man.  Kelly had led Oregon to new heights and outstanding records for the past four years and will bring his innovative fast pace offense to Philadelphia, replacing Andy Reid, who is now at Kansas City.  Kelly has no previous NFL experience.  The Chicago Bears hired Montreal Alouettes head coach Marc Trestman as their new head man.  Trestman was a longtime assistant in the NFL before becoming the head coach at Montreal, where he has spent the past five seasons, and led them to two Grey Cup Titles.  He was offensive coordinator at NC State from 2005-2006.  And the Jacksonville Jaguars announced Thursday they will hire Seattle Seahawks Defensive coordinator Gus Bradley as their new head Coach.
