Even though Searle is publicly copping this one 'on the chin', I would suspect that he would privately be pretty angry at the result. I can't understand how Carney could travel all the back to Australia, then retire after a single day's training. Obviously he knew that he couldn't last the season, so why bother putting everyone through the charade?
You would have to theorise that Carney knew months ago that he was struggling with motivation, as the whole ordeal over a 'Visa problem' can now be quickly put to bed (media reports suggested he was trying to get out of his contract BEFORE he retired today). So why didn't he do he best thing by the Titans and inform them months ago? To do the best thing by the Titans would have been to give them plenty of time to find a suitable replacement, not leave the club in the lurch only weeks away from the season's start.
Asking the Titans not to release him from his contract is, while honourable, not very helpful to the Titans 2007 season.
