It's all so confusing. No sites agree on almost any salaries and AAV numbers. I used to trust cots, but they seem to be wrong a lot.
If the money was even, I might think of the trade of Masa & Hicks for Arenado, as bad as his bat looks, but only because we free up a roster slot. Sure, a simple DFA could do that, and we will have Houck's slot open once he hits the 60 Day IL when the season starts.
I don't think we have a 40 man roster crunch, but we kinda have a 26 man crunch, especially if we add an infielder without trading an OF'er. One thing that works is starting the year with Casas and or Masa at AAA to see what we have with both. There is no hurry to trade one, now.
Even if we sign Bregman, Bichette, Okamoto or Suarez, we can easily DFA someone else.
