I have never liked Gavin Henson at Fly Half.
Either 12 or full back are his positions, but he has to be given the chance to gain some consistency at any of these positions.
He's been msessed around in regards to positions for a while and its reflecting in the way he plays.
He's playing at 10 right now and i think it's showing that he doesn't have the brain for the position. He struggles with the game, thinks over things too much and in the time he's trying to make decisions he'll simply drift across the field reducing space for his players and usually kicks aimlessly or passes to a static player, leaving the aim of making the gain line a very difficult prospect.
When he does gets his spouts of genius, when he does create absolute awesome moves it's usually in the role of an inside centre.
Why play him at 10 for Ospreys when he can't settle there and then if he does get picked for wales will either go 12 or 15?
