Family and friends remembered former Bears safety Dave Duerson during a service on Saturday at a southside Chicago church. Duerson was a generous man whose caring nature belied his reputation as a ferocious hitter on Chicago's 1985 championship team. He committed suicide last week at his home in Sunny Isles Beach, Fla. He was 50. The New York Times reported that Duerson had sent text messages to his family asking that his brain be examined for chronic traumatic encephalopathy, a degenerative disease tied to depression, dementia and suicide.
