And seriously, if you've got stats that can accurately quantify flyhalf performance I'd love to see them. Hell I'd pay to see them, would be an incredible resource.
Plenty of indicative stats available with a quick google depending on what measures you are wanting to look at. It does provided you with a fairly clear indication of the level of involvement of a flyhalf in a game and something from which to measure.
The other method is simply read how many punters in the forums didn't think his performance was up to scratch and that should give you a pretty good idea.
