Muthiah himself is a successful industrialist and is known to be a shrewd businessman. This being the case, the BCCI could well settle for the Chappell as a compromise candidate. He is a big enough name in cricket circles and yet should not cost as much as Marsh. When Marsh does arrive in India, one question will settle the issue. Having said all this, one must remember the number of surprises, even shockers, the BCCI has pulled off when it comes to selection matters.
Speculation is dangerous at best.
In this day and age, betting much more so. But throwing caution to the wind, and being partial to a wager, my money is on Gregory Stephen Chappell.
