Well, there are already some recent attempts at AFL management aside from the commercial disasters (Keven Sheedy's AFL Coach sttill makes me shudder):
First is TAR:
http://www.stratagemsports.com.au/index.html It was formerly a commercial game, though I can't understand how people would pay for it. There are some nice ideas, such as hiring staff for recruiting, admin and the like, and a very clear game interface, but it seems quite shallow.
Second is Footy Fanatic. The new version of this looked like coming some time after Duke Nukem Forever, but appeared quietly at
http://footyfanatic.net/ It has a clumsy game interface and no editor, but is brilliant from a stats perspective.
