"We don't do walking away" doesn't mean "I will never play for anyone or do anything that isn't for Rangers" Walking away means giving up, not standing up for what you believe in and losing the fight. Boca and Edu signed over, allowing Rangers to continue the fight and stay strong. Soldiers will fight till they die, but tours of duty don't last forever. They have done their bit, and can now go home to fight another day. Whittaker and Naismith however, are deserters.
