You have to give Vettori credit for being positive. He said something like "we can worry about having a tail that starts at 8, or we can tell the top 7 to front up and do their job". If the top 7 pull finger and rack up 400 (unlikely, but that's their job), then 20-30 runs from the bottom 4 ain't so bad.
That's Dan's reckoning. The problem is that the top 3 are almost as unlikely to score runs as the bottom 4, which leaves only four batsmen (Taylor, Guptill, Vettori and McCullum) to do all the run-scoring. Of those, Vettori is a bowler who has over-achieved with the bat, McCullum is extremely hit-and-miss, and Guptill has one decent test innings behind him, against Bangladesh.
As for the bowlers, we have a has-been-who-never-was strike bowler in Martin, a wet bus ticket in Southee, a decidedly average 2nd spinner with a first-class average over 40 in Patel, and a one-cap medium pacer in Arnel. Frightening? Yes, but not for the opposing team.
This would be bad enough if we were fronting up against the West Indies or Pakistan, but against the Aussies? These lads will all need to play the game of their lives to even scratch out a draw ...
