#HTTR… via National Post Sports: ”Robert Griffin III knows he’s getting criticized for playing hurt in the Washington Redskins’ playoff loss. On Monday, he offered his latest defence on Twitter. The rookie quarterback tweeted: “Many may question, criticize & think they have all the right answers. But few have been in the line of fire in battle.” The Redskins were awaiting the results of an MRI on Griffin’s right knee, which he re-injured twice during Sunday’s 24-14 loss to the Seattle Seahawks.”
