*Editor's note: This story has been updated.So much for no major changes.Just days after head coach Jason Garrett said he didn't anticipate any significant changes to the Dallas Cowboys' coaching staff -- a topic he later spoke more vaguely about -- the club released a statement from Garrett on Friday announcing it was parting ways with offensive coordinator Scott Linehan."This was not an easy decision because of how highly we regard Scott Linehan as a football coach and as a person," Garrett said in the statement.
