Buffalo reaching out to Shanahan??

The Buffalo Bills intend to do a comprehensive search for a new head coach and will consider all options -- even mega-coaches such as Mike Shanahan and Bill Cowher -- according to team and league sources. According to a report on ESPN, the Bills made contact with Shanahan and intend to set up a meeting with the former Denver coach. A coach outside the "A-list" who could fit the Bills' profile is Jim Haslett, the former Bills linebacker and former Saints head coach. With all the possible openings after the season would any of the "A-listers" consider Buffalo?
