Fans expectations change with the times. Owners always want to give their fans the best experience possible. Whether this is better seating, the video and the sound quality is through the roof, the positioning of all the seats is better, these
are priorities for all NHL organizations.
In contrast, the Oilers organization funded the entire project for The Rogers arena entirely by themselves with no government help. I do find it odd that the Flames would get money yet the Oilers would not.
