Spelly,
I can't recall when Ginever was appointed but I would be interested in comparing the coaching records of Ginever vs Hill.
Hill was appointed from the 2005 season IIRC.
Not sure what stats you have, but things like wins/losses per year; premiership ladder placings; average points kicked for and against per season; no of players used; average winning/losing margins; finals games played/won/lost etc.
Year by year perhaps, then an overall summary?
I don't want you to spend a month locked away doing this - just see what you have in easy, useable form and what sort of summary info you can come up with (if possible).
