You're only proving my point, conversely no way anyone would assume the Sox are automatically spending 30 extra million a year in 2020/2021/2022/2023. You have to add/subtract from somewhere, my point was to illustrate how futile it is to use a players contract years after being traded away with team control years. That's a fans play, and in that spirit, my comment is very reasonable.
And picking his worse season? lol dude, I picked the last 3 seasons, was I supposed to skip it? again, just another point in this being futile and subjective. And even if they still sign Arroyo, how much FWar does he really add, and to the point of my comment I can take out and add guys in there as I see fit, it's subjective. 30.4 million is 30.4 million and it's equally reasonable if not the most to assume that money goes somewhere.
I wish the Mookie trade didn't happen, but the valuation we use against it doesn't make sense to me either, it's wrong. That doesn't make it a good trade by any means, those two comments aren't mutually exclusive.
