Three one day internationals outweigh two years of heavy domestic scoring?
The reason I bring up Neil Broom is that the selectors did the exact same thing with him that you want the selectors to do with Williamson, they gave him 15-20 ODI games and then decided he wasn't good enough to play test cricket on the back of it. While you can sit there and say "he's younger, has a better record etc etc" the exact same thing could happen, Williamson may have to come into this one day team batting at six or seven and seeing as he's no late hitter he might do just as bad as Broom has done attempting it. I have a major problem when selectors do this type of thing, you should never judge a player going on different forms of the game, Martin Guptill's another good example of this.
Not sure where you get three one day internationals from, I said give him 10 - 15 over the next summer, if he doesn't do so well you can bring him back into the DOM level for one season, and then next season (2011/2012) he'll still only be 21 and hopefully the extra year of DOM cricket would of done him a world of good.
I don't see any room for him to bat at six/seven with the likes of Elliot, Styris, Vettori, Hopkins all going for those spots.
The only place I see them playing him is at three ahead of Guptill, or when McCullum or Ryder aren't playing.
My point with Broom is he just looks all at sea when he bats. I've never been a fan of him, infact I'd go as far as saying he has been the worst selection IMO over the past year. (I know someone is going to post a worse one now)
Yes I agree with you to some extent that he shouldn't be discarded from test cricket if he fails at ODI cricket, but is what I'm saying is he's still 19 so if you bring him and in and give him a taste of ODI cricket and he doesn't do so well, you can still drop him back to DOM cricket and one or two years down the track he'll still ONLY be 21 and probably be a much improved player.
On the other hand there is an equal change he'll play great and not get dropped back to DOM cricket, which is what I'm hoping for, and I assume you're hoping for.
