Brandon Marshall plans to take 2012 second-round pick Alshon Jeffery under his wing this offseason, training with Jeffery in South Florida. "I'm excited because this kid has the potential to be an All-Pro one year," Marshall said. "If he just changes some little things, the way he approaches the game as far as physically and mentally, he's going to be a beast. Because he has that dog in him, he has that in him, that you want in a receiver." The Bears are desperate for a complementary receiver to emerge opposite Marshall.
