Last year was also though, where this year may be a bit more unique is perhaps how popular they were and how the pricing seemed to almost force our hands a bit towards them meaning we experienced them a lot more.
And I dare say that the trade boosts have fundamentally shifted the entire game in this regard. Having 9 trades available from round 3-5 to correct means you really shouldn't miss too many.
I think it's also a lot easier to pick them than it used to be. 5 years ago it was basically "player moving into the midfield" which was always a complete minefield on incomplete preseason information and load management on stars. I think that one is still the hardest to pick but the move to HBF or the move to ruck are both very easy to pick/see and very lucrative and most teams aren't going to waste minutes in those roles if they're not to play there, ruck synergy is too important to waste on the VFL ruck, the back 6 synergy and kick-in strategy is also too important to waste on someone playing elsewhere. The returning from injury with a history of premium scoring is also very easy to pick, especially if you target "spike scoring" more than average.
Picking the breakout guys is still really hard, especially midfield based, picking a Green over a Caldwell for example is definitely a coin flip (albeit, Caldwell still a very decent cash cow pick), a lot of people picked Butters, albeit his durability is his biggest issue, picking a Sinclair or Houston (as someone who has picked Houston several times) over a May, Heppell or Hind type who regresses is a crapshoot, the breakout backs just seems so random most of the time.
If you apply 3 rules though:
1. Structural position change
2. Premium spike scoring history
3. New club, specific role
I think with the above 3 you'd nail 95% of the past couple of years value picks. It's not foolproof, Whitfield absolutely fits into rule 2 for example but you'd hit far more often than not.
I also don't think there will be as many value plays next year, one of the things that has been more unique the past two years, imo, is the amount of much cheaper value plays. Whitfield priced at 90 odd is 15 points undervalued but also has no scope outside pure premium. Caldwell at 266 is solid enough and makes 150k. Take 5 of Caldwell and have 3 make 125k, 1 push premium levels and 1 bust and you've done brilliantly out of that initial investment. The past two years it's been insane having Brodie, Ziebell, Coniglio, Dale, Gresham, Curnow, Hind, Cumming and a few others put up often genuine premium numbers is over the top but there will always be one or two of them.
