I really wish he wasn't going for all the reasons others have already articulated.
One thing I do wonder though is that as well as the immediate pay packet (which may not be that much more than at Souths) being a (potential) dual code international gives him more chance of career longevity in the sport beyond his playing days i.e. there are a limited number of coaching and media jobs in RL but many many more if you have expertise in league and union.
It would be revolutionary if they bolted a basketball hoop onto the front of the cross bar and you got 3 points for chucking the ball through it (or a thousand for drop goaling it through). But it isn't a good idea.
