But the TPA's throws that system out the window
Trying to produce as much home grown talent is far more important and some judicious buys from outside the square is important
You may have to pay overs on occasions to get that one important square peg for the square hole
i could be wrong, but with a 'Moneyball' methodology TPAs dont throw the system out the window at all; it is an intrinsic element of the overall assessed "value" of a player, what it will take to get him and what you are willing to pay for him (with an emphasis on value for money, if you get me).
also, the idea behind it is that you scour the available talent so that you do get that square peg for that square hole, but do so by snaring a player you see something in that generally others dont; ie; "undervalued", but with regard to your specific needs quite valuable indeed.
so these trades are the judicious ones you mention.
My point is if you can find the right player and someone to cough up the money in the form of TPA they are worth far more than another player of the same value that won't attract a TPA
People seem to get the net worth of a player and the salary cap value worth a player mixed up
