Having read some of the AFL Prospectus while on a 2 week break that recently ended (yes that's what I do on holidays), I feel I'm in a good position to comment.
Things to note:
And for those interested, the categories used by CD are: (this year anyway, they seem to change every year)
Things to note:
- The rankings are based on the Champion Data ratings, aka the SuperCoach scores. While it is heavily dependent on basic stats such as kicks, handballs, marks, goals etc. there are a lot more factors than come into play, but which CD does not care to reveal (except to say there's about 140 categories which is constantly being modified and added to).
- The analysis is done over a 2 year period (with 'greater weighting towards 2012' but no specific numbers are mentioned), Pierik does mention this in the article but almost in passing: Elite players are in the top 10 per cent for their position. Other categories were above average (top 35 per cent of position), average (middle 30 per cent), below average (bottom 35 per cent), poor (bottom 10 per cent), while players who had managed five games or fewer in 2011 and 2012 were only afforded a question mark.
- This is why players such as Jetta only rate as "average" as his 2011 is a significant anchor dragging down on his "elite" 2012 output.
- The introduction of the sub rule in 2011 has played havoc with CD ratings as a player who comes on during the last quarter of a game will have an extremely limited amount of time to make an impact. This is why we see Rohan and Parker in the "below average" category because they have served as the starting or finishing substitute numerous times over the past 2 years, and their shortened game time brings their averages down.
- In any case, these are ratings based on what a player has performed, not based on his potential. Parker, for all the glimpses of talent and the great hopes we hold for him, is still very much a fringe player in our midfield rotation and I don't think a "below average" rating (he's on the cusp anyway) is too unfair.
- CD also recognise the limitations of their system in ranking defenders, in particular the key ones, (The 2012 CD Team of the Year had Scott D. Thompson and Michael Johnson as their key backmen as opposed to the AA version with Teddy and Luke McPharlin) and asked their staff to rank the defenders subjectively. I believe this is the only exception to their numbers-based approach
- And lastly, while it's true we don't have a "poor" player on our current list, we did have one player over the 2011-12 period (shown in the linked article). We must have traded him out so we could claim to have zero "poor" players
