New DC Dave Wannstedt has singled out MLB Kelvin Sheppard as a nucleus player on the Bills defense. "I've got all the confidence in the world with Shep," said Wannstedt. "To me he's about what you're looking for in a 4-3 middle linebacker. ... I think it's going to fit his skills to a 'T'. I think he's going to be a very, very productive player for us." Sheppard is going to be a player to target in IDP formats in 2012.
