My definition of being an elite midfielder is someone who has dealt with tags and constantly beaten them. On that basis, only Pendlebury, Ablett and Watson have done that in recent times and are what I regard as "elite". There are tonnes of players that run rampant without attention and look like superstars, i.e Johnson, Jack, Stanton, Barlow, Deledio and Hodge but until they consistently attract taggers week in and week out and beat them, it's hard to put them in the same category as the three I mentioned.
Would add Mitchell and J. Selwood to your list. The rest are just A grade (which is still pretty damn good).
I am just sick of people calling Swan elite. No where near Pendles. He is to Pendles as Nathan Burke was to Robert Harvey. Runs hard get plenty of it but not enough class to finish off right.
