Well yeah, you can't just pick every player based on history. Nobody is picking Green or Bruhn or Gulden or Flanders based on past averages, but because those players have shown obvious signs of improvement in the pre-season that would indicate their scoring is about to go to another level. Whether they will is another question, but that's the risk/reward.
I get the argument that Flanders isn't underpriced due to injury but because he's been crap at AFL level, but again, that's the risk/reward. I think he can score well beyond the 48 he's priced at.
I only brought up Allen's past scoring because without context his 78 avg season looks great, but with the context of him playing a completely different role that year, that 78 average becomes less relevant to his potential value this year. Without that role he's shown to be a 65 average player. I personally can't see Allen being worth it, especially given how bad WCE are and how tough their draw is R3-R8 which are the prime money making rounds. If you think Allen is a good pick then don't let me stop you, I just don't see it the same way.
