Yeah winding down at 32-33, give us a spell! That's 10 years of winding down according to Baker and Gibbs.Rosbrook is about 33 isn't he. He's probably starting to wind down, and sees at as a good chance to finish up playing with his mates from Carlton, and earn some more money whilst he's at it. If thats the case you can't begrudge him.
Its a free market. And if guys are playing at your club for money, you need to accept that they may move on for a better offer.
