Yes, I don't believe halves have to be world class defenders. Certainly helps if they are, but as I've said already their job is to create points. The aim of the game for 125 years is to score more points than the other side and the halfback is instrumental to that. We had no halves last year that could create points. We let go of the only halfback that was capable of that and he took his team to semis footy last year.
I'm perfectly fine with all our halves from last year being moved on. Brooks was probably the better defender out of them all but couldn't do the most important part of his job right. Doueihi can't do either, he can go too.
And I don't own a Segway, only goofs and hipsters ride those. I think the word you're searching for is "segue." If you're going to be a condescending wanker it probably helps if you use the King's English so as to avoid looking foolish xo.
