I'm confused about what you're looking for here. Are you looking for suggestions that are based on the current value of the player at the time he is named as a keeper, like maybe 10% of his current cost rounded up?
I don't quite understand why you discarded hersch's suggestion as "arbitrary." It didn't seem arbitrary to me. It was a fixed charge, but it just wasn't based on the value of the player.
Anyways, maybe you can clarify what you're looking for a just little more for me? I'd be glad to throw out my two cents, but I want to make certain I know what you're looking for.
I'll try to explain why I'm not in favor of a flat fee for all players.
To pick a flat amount seems arbitrary to me. A $5 dollars increase has significantly different meanings to different situations. Say for example that there are three players drafted at $50, $25 and $10.
In the 3rd year of the league a Pujols type player is now $60??? And well this may work for your middle tier guys it certainly doesn't seem right for WW players that come up in the middle of season like King Felix and Wright type players. So I can have King Felix or Wright in the 3rd season for approx $20 b/c my WW position was 1 better then someone else?
What I'd really like to replicate, if it is at all possible, is something similar to real ball. For instance, Manny's next contract is not going to be growing by ~10% each year. I'd something that limits the keeper taxes or fees on players that have already peaked, increase for those are peaking and have modest gains for those who are middle of the pack role player
A crude idea that I'm tinkering with is havign a prorated tax based on last season's draft value.
What I'm hoping to get from the cafe is some examples of non-flat fee taxes with the hopes of modifying them for my own league.
Does that help Mr. Wood?
