Yes i'd agree to some extent that he is over rated. I remember being a season ticket holder at Neath back when he first "popped up". His promice was something spectacular, but as usual with talented welsh players, their own versatility is their own undoing, combined with extremely poor man management. The O's fluffed it with him, and so have Wales. They've fluffed about with his playing position, and he hasn't been able to "settle" in to one position.
If Wales are to play him at 10, then we need to have a scrum half that can pass so Hook is given a few more milliseconds to react to whats in front of him. The welsh public have expected miracles from Hook, when the real downfall (when it comes to the whole backline in general) is the fact that we've had poor distribution from rucks/mauls etc. You give Dan Carter **** ball, he wont produce miracles. Saying that, Hook as yet has not fulfilled the stupidly high billing he's been given. Time will tell i guess
