Yeah, but see, the Pens have made more progress in the past 3 years than the Pirates have in the past 15. Name the last championship between the two? Or how about, the last winning season?
No matter how you spin it, there is a large and faithful fan base behind the Penguins here, in Pittsburgh. Larger than the Pirates. If there was a team to be moved based on least fan base behind the team, it would EASILY be the Pirates.
