‘Northern, who will play this week at defensive tackle in a nickel-defense situation, has been working with some of the Vikings’ coaches, gladly surrendering all the information he has on the Bills’ scheme and their personnel. "In practice, I might see something and point how the Bills do it," Northern said. "I practiced against that offense and I know it pretty well, so there are some things I can help with . . . I’d love to help us expose something that directly helps us win the game." Lacina and Paup (who is out for the next six games with a fracture in his knee) have talked to their teammates about the habits of some of the Bills’ players. "I was talking to Johnny (Randle) about some of the Bills’ offensive linemen," Lacina said. "I was around those guys and know a lot of their little secrets. Knowing the personnel is big part of playing a team."’
