Adelaide coach Neil Craig tips West Coast to beat Sydney in Saturday's grand final - 'but not with any sort of confidence'."How could you pick it?" Craig said on Friday. "If you look at the history between the two clubs, I mean, it's been decided by a bit of luck in a lot of those games. Even the last game, that ball that comes into (Michael) O'Loughlin, it either sits and rolls for him or it sits and goes back over his head."I think it's going to be a great game. They're establishing a real rivalry among themselves, they both play tough footy. If you had to make a choice … I don't know … if (Daniel) Kerr stands up and plays some reasonable footy … I saw last year's grand final and I thought it was significant when he went off the ground."I'd say West Coast, but not with any sort of confidence, if you like."
