I refer to a posting on Ben Mowen I did back on 2/10/13 which I'm copying in here. This was prior to his appointment as Wallabies captain and European tour, but the logic is even more obvious.
"Back to Ben Mowen.
As Brumbies skipper he'd have to be earning close to $400k there. Plus say 10 games this season with the Wallabies is $140,000. So he is getting over $500k p.a. plus some sponsorships meaning probably $550k to $600K.
His problem (and his manager would know it), is that when Pocock, Higginsbotham, and Palu come back into the side, plus up & coming younger players like Gill & Wil Skelton, then Mowen could be out of the 23 group.
Therefore less game payments. So he's striking while all his planets are aligned. But the ARU would also be aware of the situation, and I can't see them falling over themselves to give Mowen a top up.
In fact, in cases like Mowen's I think the two year top up rule is a good one. If he's good enough, he'll be in the dough. If not, then 'bon voyage', if that's what he chooses to do."
Time changes some things, but not his reasoning regarding his future. The thought of rooster one day, feather duster the next, would be hard to live with i.e Wallaby skipper to not in the squad.
Who wouldn't go for the big lucre offered overseas at this stage of their career.
And yes, a chance to experience the world with your family - good luck to him, he's been a good servant of Australian rugby
