Im not a fan of the mobile only option, especially for season ticket holders. I thought the card system that they have had in place is a much better option and I'm disappointed they are going this route.
By utilizing mobile only ticketing, they are saying "f*** you" to the people like me to who do not own a smartphone. I do not even know how to use a smartphone, nor do I want to know. When I attended Florida Panthers at Philadelphia Flyers this past November, I was thankful that they allowed me to bring the printed P.D.F. of my stubhub ticket.
The fact that the stereotypical sports fan knows how to use a smartphone does not give the powers-that-be the right to impose that stereotype on all sports fans.
