It doesn't have to be an either or choice.
We can win it all with HRam being rested and sharp for the playoffs. It might even increase our odds of winning, if HRam does not vest and is fully rested for October.
If HRam seems to be an essential factor in us even making the playoffs (or winning the division), and that has yet to be deterined, then yes, we have to make a serious choice about choosing "sunken cost" for 2019 in order to win it all in 2018.
What if HRam gets 650 PAs, we win the division, and then he looks tired or burnt out in September and October?
Is that a possibility?
Do the odds of him getting injured go up by giving him 600+ PAs vs 495?
It's not as simple a choice as maybe some think it is. It's not black and white.
