The whole "Crocs camp didn't want to pony up the dough" is crap from what I understand. Luke had a player option at a salary in the top 2-3 players in the league and all reports was that he was going to take up that option(according to the Crocs CEO, 80% chance), then when the day the option expired he decided to walk.
The news article makes it sound like he has cut all ties with the club, but I feel like its probably his agent in his ear hoping to get 10% of a bigger pie testing the market. As said before, this came as a bit of a shock to everyone at the club as it appeared Luke was very happy there. As a Crocs supporter I would love it if he had a change of heart and decided to stay, but I doubt the club will be waiting for this and instead pursuing other opportunities as they arise, Hopefully for the betterment of the team.
