Green Bay - During the Mike Holmgren era, the Packers almost never practiced outside in the cold because he thought it was more important for the players to be focused completely on their preparation and not on how much they wished they were inside.
After staying inside in 2007 and then taking a beating from the New York Giants in frigid temperatures at Lambeau Field in the NFC Championship game, coach Mike McCarthy has changed his tune and started practicing outdoors with a cold game approaching.
Most of the players aren't thrilled about practicing outdoors
Though they don't like it, they do recognize there's a purpose in practicing outside and they admit that after awhile their bodies get used to it.
