( Tiki Barber , Jeremy Shockey , Plaxico Burress , Amani Toomer and Brandon Jacobs ) . While Hufnagel is credited with the rapid development of quarterback Eli Manning , he is sometimes criticized for his often predictable playcalling and an inabiltiy to utilize his offensive playmakers effectively . During the 2006 season , Hufnagel came under much criticism for being too pass - happy and abandoning the running game after the Giants trailed during games . In addition , he was also questioned for having Manning throw the ball the third and sixth most passes in the league over 2005 and 2006 despite Tiki Barber clearly being the best player on offense . In addition , his situational playcalling came under scrutiny , such as when running back Brandon Jacobs was removed from the game inside the five yardline in two games , thus making the offense more predictable to opposing defenses . Following a 30 – 7 defeat by the New Orleans Saints , Hufnagel was stripped of his duties as offensive coordinator . A week later , it was revealed he was fired . On December 3 , 2007 , Hufnagel was hired as the head coach and general manager of the Calgary Stampeders .
