Its sad, not just Ervine-Blignaut, Goodwin, Neil Johnson, Grant Flower, Andy Flower, Carlisle, Vermeulen, Travis Friend etc. All of them left at some point, some returned, some didnt. With better administration they could have gone long way ahead.
But they have a knack of developing good players. Brendan Taylor for example could have become something special. But lack of exposure has stunted his growth. Kyle Jarvis is another real talent who hasnt progressed. Bryan Vitori is another talented bowler. I bet we could have benefited from such quicks.
