My thoughts...
1) People need to also realise that attitude plays a big part in selection. If a player has a bad attitude, they may not be selected. One would be wise to remember this - Andre Adams was at one point dropped from the NZ side because of his bad attitude. I don't know if Parore and Cairns were ever dropped, but it must have almost happened on at least one occasion, and those are two world class players of their time (Parore was considered the best keeper in the world at one point, Cairns the best all rounder at many points).
2) Hoy, Cunningham and Wilson all deserve a decent shot.
3) I agree with the fact that we're a young side and should not expect to win tests too easily.
4) Having said that, we are still in the baby stages of our Dev League, too. Five teams is hardly a large league, and I imagine that in the 9th season of Australian cricket, rookies wouldn't have as hard a time making it into the squad as they do in this competition.
5) Having said THAT, I agree with Pickup that players should at least be active. But if they're active and they're highly capable, they should be given a chance. Daniel Vettori, how do you do?
6) It's also notable that Bangladesh selects a very young side. Sometimes relying on old members isn't always the best strategy. A mixtuer would be best, I find, in these still-young stages of CWLand.
7) Activity and involvement, meanwhile, should not be the only qualification for making the team. I will admit that every time I'm selected, I find it a bit strange that I am put ahead of other batsmen with far higher averages. I didn't even have an OD century when I was selected. I'd barely got above 70, I believe. I think I'm better now, but I do wonder what's going on in the heads of the selectors when I can make the OD squad in my second season, yet players far better than me struggle to.
I think the selectors need to take a few more risks, and if they do take them, they need to stick to their guns longer than a couple of games. If a rookie bowler gets smashed around the park, it's not the be-all and end-all. Give him/her a chance.
