thats both a really easy question and a nightmare. its a clear cut chance. After that it gets into a whole other debate, best summed by Maidel:
For me, the problem is what defines a CCC, and as its a computer it has to have specific boundaries as to what is a CCC. If you listen to match comentaries in real life you will hear the commentator scream 'he missed a sitter' or words to that effect. In the game that would come up as a CCC. However if you watch match of the day often the people in the studio will disagree over how easy or hard a chance was. They will defend a player saying 'well he was leaning back to much' or 'he was already stretching for it' or such like.
Thus in real life there are no stats for CCC because it is entirely subjective.
I think we all suffer from 'highlights syndrome' This is where we are all used to watching match of the day or other such programs where they have to squeeze 10 games into an hour and half show (or is it an hour these days?). Thus, pretty much every time they show a clip you KNOW something interresting is going to happen in it. We will miss all the long shots that scream off towards the corner flag or the really neat passes that got towards goal, but was eventually uneventful.
A very specific example of this is roberto carlos - he is not the greatest free kick taker in the world - but his single unbelievable free kick has been ingrained in our minds so strongly that often that is the first thing people think about when someone says a free kick specialist. We are far too influenced by what we perceive to be true, rather than statistically what is true.
