Just wondering, whether they'd been trialled in any sort of cricket before their implementation in One Day Internationals. I never remember hearing anything about it, and with the amount of teething problems that they've had, and how some aspects of it haven't worked as the ICC, and the teams, would have liked, there has seemed to have been a lot of "trial and error" about their implementation.
This, IMO, could end up being largely responsible for their possible withdrawal from use after the ICC's review in Januaray (which, I personally, hope takes away both innovations). But in essence, I just wish to know whether they'd been trialled in any sort of cricket before international stuff. If not, that's an enormous mistake by the ICC.
