I thought I'd pick up the suggestion made by archie mac elsewhere and start a thread on cricketing "what ifs".
There are various ways of doing this but I suggest each poster answers the "what if" and then posts their own. Answers can be as long or as short as you want.
So to get us started:
What if Ashley Giles held onto the catch offered by Ricky Ponting at Adelaide in the 2006/7 Ashes?
