Twitter mourns death of NFL great Junior Seau

Much of the reaction on Twitter about the death of Junior Seau, one of the most accomplished linebackers in NFL history, who died today in an apparent suicide, was that of shock and grief. But as has been the case in many recent deaths of former NFL players, some also speculated if Seau, who had shown signs of erratic behavior following a 2010 arrest for domestic violence, suffered from the kind of traumatic head injuries that have been linked to numerous deaths of former NFL players, including Dave Duerson's suicide in 2011. In an unrelated and strange twist, Seau now is the eighth member of the Chargers' 1994 AFC Championship team to have died.
