Just because a poster is a Bills fan (and we do have some contributing and non-contributing other team fans on this board) does not mean posters do not follow other teams. Some have season tickets in other stadiums! I was also a Green Bay fan when Hyde was a free agent and I recommended the Bills sign him before he even visited Buffalo.
Note on Vikings: I was offered a job in Minneapolis for a firm which paid for moving expenses. One of the benefits I was told was they had a stadium box and employees got to use game seats on a rotation basis. During the 3rd interview I was being pressed whether I would take the job and asked "Could they put me in touch with a company which would help me and sell my house for me?" I told him I could not do that because my wife needed time and my daughter needed to finish the school season. I told him I could go there first and sublet a place and I was told "No. We are a family-oriented company and we expect family to move with you when you accept the job. Any more questions?" One more I told him - I am a Packers fan and can I specify my game be the Packers game and he just replied no. Interview ended at this point and I got one call from HR stating "Interviewer got the impression you were no longer interested in the position because you are a Packers fan. I can understand that for I am a Bears fan." I told him it was not the primary reason but when I told him I was a Packers fan he ended the interview.
