That was done at a signing held for Season Ticket holders in Edmonton over the weekend. I'm sure the players have a right to refuse some things - but being a team event, it might be a bit harder to do to turn down.
Given what Katz is charging for tickets these days - and basically a 40% price increase from 14-15 prices to 16-17 into the new building - there better be a lot more perks to being a season ticket holder besides a signing...
