Not to defend the Krafts, but the Maras did force most of their season ticket holders to fork over thousands of dollars (in some cases, tens of thousands of dollars) a little over a year ago for PSLs. Delaying them paying their season tickets until there is more certainty for games is the least they could do.
As for Kraft, he lost me defending him on tickets prices and payments when he started to force all their season ticket holders to only buy their tickets using Visa. I know he had a deal with Visa, but it is very unconsumer friendly to force people to use a card they may not want to use to buy tickets. Spending thousands of dollars a year on season tickets, I would want my rewards points.
