The Vikings' first-round draft pick, running back Adrian Peterson, has been everything Brad Childress expected, the coach said Tuesday. "Exactly as advertised, and probably one better in terms of catching the football," Childress said. "He has spent a lot of time with (running backs coach) Eric Bieniemy; he lives in his hip pocket. He is hungry for knowledge . . . he's a million-mile-an-hour guy; you have got to slow him down at times."
