I actually like Utah more than most posters here - good memories growing up rooting for them with my Dad (he's an alum), so was a big Utah fan until I went to BYU.
And when the NFL was consolidating I bet a lot of teams left disappointed fanbases. The Canton Bulldogs and Dayton Triangles didn't all become fans of Cleveland overnight... but I can't think of the last time I met a Triangles fan.
To be honest, I agree with you and don't even believe that... but it's what I think the power-that-be may be thinking
