My only problem with the trade is if they fail to execute the plan going forward.
You want to deal elite prospects? Fine. But then don't pinch your pennies and let Berrios, Ray or Semien walk if they want to be here long term. Don't pretend to be a big market transitioning into win now and then go back to being conservative.
Keep drafting and developing prospects so you have more of them to deal for help now and pay the money to keep this team competitive.
They made good commitments to Ryu and Springer, but they're going to need to pay Berrios, Ray and Semien or someone like Thor or another infielder to replace them to commit to being as good next year as they are to finish this year.
And when it comes time to pay Vladdy and Bo, don't lowball them. Write the cheque and be happy to have a winning team that will make a lot of money in return.
