Whilst I agree with the sentiments and some of the reasoning in the article - a few issues come to mind:
1. Cricket success is about great batting, bowling and fielding by the TEAM [as well as Leadership of course] in the 1st place - on the day of play! Having good management or backup players in the wings is secondary on that day. All these aspects must have focus all the time and perform consistently to achieve continued success
2. The failure in Durban was a disgrace by the TEAM - not Management or the players in the wings.
3. The Team should have a reward/penalty scheme in place that rewards "consistent" player performance and hurts in the pocket when they fail ~ the performance curve must always be either flat [meeting our high expectations] or upward [improving on the last performance]
4. Bowling consistent "rubbish" which the opposition can ignore is of no value to the TEAM, they don't even have to field these deliveries! All the bowlers did that, not just Ntini! He was only picked by the selector's to satisfy the media and give him his 100th+ game, his previous 5 games performance certainly did not warrant his selection. This was Management's [the SELECTOR'S] error, not the TEAM!
4. Throwing your wicket away by poor shot selection is also of no help to anyone - this is what the TEAM did in Durban - no excuses. If England can hang on for two days in Centurion and Cape Town, up to and including the tail-enders - where is the SA TEAM's focus
5. Dropping catches and poor fielding is unacceptable - ALL THE TIME!
6. We have to get everything right - not just a single aspect of the great game!
