I'm thinking about putting a lazy $20 on NZ to win the damn thing. I probably sound crazy but I have a good feeling
I was actually thinking the same thing yesterday, considering we have a 99% of chance of making the quarter finals, 15 to 1 are bloody decent odds.
The three teams IMO we need to avoid (until the final) are Australia, India and Sri Lanka. Australia always turn up to play at World Cups (IIRC they've won some stupid amount like 17 World Cup games in a row), and India and Sri Lanka as the two home nations will be very tough to beat.
I'd say we're 50 - 50 against England (Yes, I think their current team is very overrated after their Ashes win), 50 - 50 against Pakistan, 70 - 30 against the West Indies, and probably about 40 - 60 against South Africa (Again I think they're slightly overrated, they don't normally preform to their full potential at World Cups, and I think they have a few weaknesses).
