Taranto was a borderline keeper though, I think people really miss how much the value aspect does shift that line. Averaged 102 until the move forward, at which point you'd be looping him with Bramble anyway and have taken Bramble on two of the putrid scores for an extra 80 odd points, which puts his average back the 102 anyway for the full season. So effective average was 102 for a switched on coach, worst case is 97 average for absentee ownership or a luxury trade come the last few rounds. Priced where he was that's about 113 worth of value in the team which is absolutely keeper level.
The issue with the above is it really only applies to a couple of players, you can only be missing so much of the premium scoring given the finite on-field spots but most winning sides I can think of will have had multiple value picks in them, be they trade targets or starting picks.
Agree entirely that the skill of spending the money is not easy and that the returns can definitely be diminishing. This year though I think there's an obvious spend on the premium rookies.
I genuinely think that Hewett at 90 and Sicily at 95 would be, at worst, luxury upgrades but realistically that's keeper territory unless the back landscape shifts significantly. That's 5/10 points a week on a Short as a starting pick but you should be generating 25 (Hewett) points a week elsewhere with the cash, and this year I dare say it's going into premium rookies so you can actually generate some cash!
Basically, those guys need to be picked as keepers barring there genuinely being no rookies (seems possible for the first time ever!) but what you deem a keeper should also be adjusted for them.
If I find said defender I'm keeping him to myself. I can't even find 2 150k defenders I think will play
