I don't think Chappell was against Laxman and Kumble. Those two are not in the ODIs, but is that surprising? You don't need Chappell for that. Hell, Kumble and Laxman have been in and out of the ODI team long before Chappell came along. But they have always been test team regulars.
As for Ganguly and Zaheer, perhaps one should understand that when they left, they sucked. And had been sucking for a long time. Now that they are back, they are playing well. Ergo, the break was good for them. Ergo.... Chappell was right.
