It seems to me that with new owners the wisest thing to do would be to run surveys looking for fan advice to improve the game experience. I don't mean just among season ticket holders either. Get the advice of your customers to find out what needs to be changed because if you make a guy who only comes to a few games a year happier he might buy a partial plan. If you please a partial plan owner he might ratchet up to a full plan. This is basic business sense that customer service is key to any business and in particular to an entertainment based business.
It's not the owners. It's the entire Devils management. They need to do a better job at communicating with their customers for sure.
