Why not just let everyone scrap it out for the 4 places instead of giving several of the sides massive advantages?
Why do you think the concept of the Super Sixes was invented at all? To stop the situation happening to other teams as that which happened to South Africa in the 1996 World Cup where they won all prelim matches and were beaten in the semi-final so were out. Their argument was that form wasn't rewarded and was in fact penalised where their one off game turned out to be the one which counted. They wanted a change whereby even if a team has one or two off days, they can still compete.
If we had it your way, we'd be reverting to a method which almost no-one was happy with and that the ICC changed for a reason.
To all the Kenyan naysayers, what are they supposed to do about being in the Super Sixes; just let themselves get thrashed saying "Well, we didn't really deserve to be here anyway"? Sure they've had some luck along they way but the reality is that they did beat two Test playing nations so they deserve to at least be in the Super Sixes.
Whether they'll compete is another matter but to say they don't deserve to be there denigrates the efforts they put in and patronises their players, effectively saying to them "You're just lucky! You didn't deserve to win." It's akin to what spoilt-brat older brothers say when their little bro beats them in backyard games and that's the exact image I get in my head when I hear all this criticism of Kenya. They're there, deal with it. South Africa and the West Indies certainly have vastly more talented teams but to infer that on THAT basis they deserved a super sixes place more than Kenya is to ignore that they did not play to their potential.
Geez, if teams deserved to go through to the finals on the basis of pure talent and not how well they played, why have a WC at all? Why not just give the trophy to the Aussies and be done with it?
To use a similar argument would also infer that India did not deserve to win the 1983 WC because the West Indies side was a much more talented side or that Pakistan didn't deserve to win the 1992 WC because they started badly and that other teams somehow 'deserved' it more. WHAT-ever................
