The same way I don't hold it against Sir Viv for not facing them I won't hold it against Ponting because you simply never know. Ponting has all the tools IMO to savage even that attack on his day - he is simply one of the best players of fast bowling of all-time. Having said that, one can't deny how impressive Chappell's record is. IMO he is the best batsman with Sir Viv after Bradman. I slightly lean to Sir Viv because of my love of flair but I'd be lying if I said Chappell wasn't on the same level. I think Ponting is a touch behind, but could share such status by the end of his career. Regardless, it isn't "easily" one way or the other for me.
Also, I'd like to look at the line-up of that WSC line-up. IIRC, the WIndies didn't have their best bowler: Malcolm Marshall.
Edit: just read
it, amazing attack: Andy Roberts, Michael Holding, Colin Croft and Joel Garner. That has to be THE best attack of all-time.
