Some Bears teammates started calling the rookie quarterback "Pretty Boy Assassin" midseason, but we prefer the nickname he brought with him to Chicago. So how did he get it? He explains: "Freshman year of college, one of my coaches was out with family friends," Trubisky said. "Somebody said my name and kind of … mumbled it. He was like, 'What'd you say? Mr. Biscuit?' … It kind of stuck that week of practice, and that's what all the boys started calling me." (Brian Cassella / Chicago Tribune)
