Ravens wide receiver Mark Clayton says that quarterback Joe Flacco has a new on-field attitude. "Yeah, he was just more take-charge, first and foremost," Clayton said of the young quarterback following Baltimore's recent workouts. "He made a comment [on Tuesday] to one of the defensive dudes, and the manner he said it, it was a take-charge attitude." Clayton added that Flacco might be headed for a big year. "Any position, you come into the NFL physically gifted," Clayton said. "You've got that. But the mental part is -- by far -- where you make your most improvement in the NFL. ... I definitely see that in him."
