I don't think I'm as high on Cox and Hughes as most on here seem to be. Cox seems like a old-fashioned footy player, which I like, but I'm not sure he's tall or fast enough to be an elite AFL player. In the right circumstances I reckon he could be handy, but I'm not sure there's an obvious spot for him in the team as constructed.
As for Hughes, I like the way he attacks the footy, but his decision-making with the ball in his hand is a bit suspect to my eye. At 23 there is still some room for improvement, but I'm not sure he's much more than an injury-replacement at the moment.
