Brandon Marshall credits the trade that sent him from the Miami Dolphins to the Chicago Bears in March 2012 as being "life-saving and career-saving."

Marshall recently signed three-year contract extension worth $23 million guaranteed.

"I don't think I'd be sitting in this position talking about an extension [if not for the trade to Chicago]," Marshall said. "I probably wouldn't even be having the success that I was having on the field in that environment [in Miami]. It wasn't right for me."
