Giving him a rest I imagine. Plus his spot in the side isn't under a question mark, unlike Martin, Gillespie, Mason, Patel or O'Brien.
O'Brien seriously has to be one of the worst players we've had for a long time. He's a classic Kiwi domestic bowler but a terrible international bowler. He's had his moment to represent his country and failed. I actually feel sorry for him, but he shouldn't be in the side ahead of more deserving players.
Gillespie I simply think isn't a limited overs bowler. Did great on his test debut and I think he'll be a great specialist in that area but I don't think his style will cut it in ODI's.
Mason is a bit odd. IMO he has great control though a bit one dimensional, but I think he has the potential to bowl better spells than Gillespie or Martin in limited overs.
However Jetan Patel should play ahead of all of them. I've long thought two spinners in ODI's is a great way to keep runs down and create pressure (always thought Sri Lanka did this superbly). Patel looks as though he can take wickets where Vettori can only keep it tight.
I think, forgetting Bond because lets face it he spends more timed injured than not, our best bowling attack would be Mills, Franklin, Vettori, Patel, Mason, Oram. Franklin has improved greatly in the last year and think he will be very good for us.
Also, I think our last match against Australia in the World Cup shows that Australia's attack improved (though it had McGrath, but then, no Lee) and was able to stop us from chasing a 300+ score. I really would love to be proved wrong but I have a feeling the same thing will happen this time round. Australia will make 350, and we'll make 250 at best.
