Bears wide receiver Brandon Marshall signed a three-year extension.The Bears confirmed the extension.Marshall also noted he’s pledging $1 million to the “mental health community.” Pretty awesome.Technically it’s $30 million extension over the three years that will pay Marshall just under $40 million for the remaining life of his contract.Marshall was acquired by the Bears in a trade with the Dolphins for two third-round picks (that looks like a STEAL now, huh?).In two years since he’s caught 218 passes for 2,803 yards and 23 touchdowns. He’s also turned around his life off the field and become a real ambassador for mental health in the sporting community.
