Being a baseball GM is actually very simple. All you have to do is bring in players who will get better going forward, and get rid of ones who are going to get worse. That is, I should probably point out, me being sarcastic. But the old saw of “Buy low, sell high,” is certainly a valuable skill to have. We saw earlier in this series how Mike Hazen was apparently able to do the latter last winter. This was in particular shown with the trade of Paul Goldschmidt, but also in letting walk away a number of players who subsequently proved unable to repeat their 2018 performance.
