I've always been of the understanding that the top 2 are Barassi at 1, Flower at 2.
I remember a big debate with all the demonland/demonology bigwigs about the team of the century, and Neitz isn't in it for last century and probably won't be in it at FF for the next century. Had Neita's career come 10 years earlier than it did would he be in our team of last century? I like to think so. Honestly though, I don't know that he'd be in our top 5. The abovementioned and Ivor Warne-Smith, Lyon, Stynes would perhaps round it out. I never saw players play before the eighties but I'm sure Dixon, Beames, Fanning and especially Norm Smith had claims.
I love Neita as much or more than the next bloke who's blood runs Red & Blue, but I don't know that he's top 5... yet.
