You can change countries, but you have to prove residency and sit out a qualification period of two years since you last played. If Pattinson moved to the UK and played country cricket and wasn't required for a couple of years he could change, but he's definitely in Australia's plans. Won't happen.
That's the point, James - I've read lots of comments about McCullum's attacking batting, but he wasn't trying to plonk the ball that bowled him. He was just pushing at it, was a bit frazzled, and the inswing beat him.
Yeah, I watched just about every game - Ross didn't have a memorable tournament. I thought he played a real Finch of an innings in the final, lots of nicks and dots and plods. Plenty of talk about his possible retirement, though I'm not sure how likely.
