I think i figured out part of the problem with the way you are looking at this and it is based in part on what i already mentioned.
you are figuring that a player should be looked at as a double salary based on how much he would save the team if he weren't on the books in any particular year.
so, yes, under circumstances TA and Posey and Scals, as examples could be viewed as saving double what their salary is by either not signing them or trading them for an expiring contract...
so you're saving double by theoretically not having them on the books in a future year, but the problem with this construct is that it is predicated on the notion that at the earlier point in time every contract that could be moved or not extended should be simultaneously viewed as a double salary....
you're saving double in the future scenario, but you're adding it on in the current scenario in a way that it doesn't exist.
that is to say, while we might say that we could save double on all these contracts by not having them at a future date, we aren't paying double for ALL these contracts at the current date.
ie we are paying 8 mil in lux tax, not 16 mil.....
Show me what you mean with numbers.
it's hard to use numbers because the problem is conceptual.
you're arguing that since the team is over the lux tax this season, any contract (either currently signed or to be signed) that is not a core player should be simultaneously be viewed as a double salary because not having that contract in those future years would save double....because again, the assumption is that in the future season we would be again over that lux tax....
while technically true, this predicated on the idea that you are viewing all current contracts (ie the money we are paying this season) as double salaries...
so yes, if we knocked TA or Scals or Eddie or POB off the books by trading them for an expiring contract or if we didn't sign any FAs in the next off season or made no picks or didn't bring over a player like Erden....what-have-you....we would be theoretically be saving double on all those moves (or non-moves), but that is tied to the notion that we are paying double on all those comparable contracts this season (ie everybody other than Ray, KG, Paul, Rondo or Perk - the core).
but the reality is that we are not paying double on every non-core contract, we are only paying double on the 8 mil that is over the tax.....
so yes, we would save double on TA or Scal or Eddie or POB or any other contract to replace ones that actually expire this year (ie BBD, Powe) if we knocked any of them off the books for next season...but we are not paying double for all those contracts this season.
the problem is sort of highlighted by trying to answer this question: who are we paying double to this season?
