I always thought Jnr's retirement was a 50/50 decision
The "good" side for Jnr was that he went out on top, unlike many others who go a year too many and somewhat tarnish their reputation.
BTW I don't think such decisions (to retire/delist) should be left upto individuals. There is far too much money at stake. A player could be satisfied sitting out a year injured or playing in the magoos for $500k, esp if he doesn't have another career to fall back on. It would be impossible for a player (captain or not) to be totally objective about his form and ignore the money.
And yes, the club could have managed it better....but then they admit that.
