I'd like to think there is some loyalty left in the game and you only need to look at a guy like Jack Trengove to know it's still alive.
Let's see if he changes his tune in 12 months time when the rumours about his contract start to heat up. It's easy to sprout about how you want to remain at the club when you have 18 months left on your current deal.
IMO Trengove will stay, seems to be in a good situation for an interstate kid being able to play with all his school friends.
