The Free Agent $8.5/WIN 2022 cost is fact. Long term deals when the bill is due and they are no longer performing prejudices your current roster with the legacy cost.
This reality just reinforces the need to develop more SP and pen arms in house and not have to buy an entire FA rotation, given the risks, like 1.5 years of 4 of effective Ryu etc. What we have now is not the sustainable model that I want to see.
