I think yesterday is a good sign that a rebuild is about to happen. Just let 2 former 1st round picks walk without any compensation is not like what this club has done before. I agree with Darvish too, love what he has done the past 2 years after enduring a rough start to nearly being a Cy Young winner this year. He and Hendricks are probably their 2 most valuable pitching trade chips, Darvish is owed 22, 19, and 18 mil a year over the next 3 seasons before becoming a free agent at age 37 so if some contender offers a nice package of prospects to take that contract off your hands it makes sense. Time to cash out on that now before he potentially becomes the next Lester situation in the rotation. Hendricks is only 30 and signed at a very reasonable 14 mil for the next 3 years then 16 mil in his last year so doubt they move him without a huge haul back because he still fits into the rebuild for now in the middle of his prime years.
What sucks right now is you won't be able to move Heyward or Kimbrel without eating a good chunk of their 23.5 and 16 mil contracts. Kimbrel is still on the books for 2022 at 16 mil too, Heyward through 2023 so neither are probably going anywhere without the Cubs paying most of that so you may as well use the gold glove in RF and hope Kimbrel figures it out. Contreras is probably the best trade asset they have, he is under team control for this year and next at a reasonable cost at a premium position and the Cubs have depth at the position. Not sure what the market is on Baez but my hopes are they find reasonable extensions for him and Rizzo then build a roster around them which is likely to include Happ (just a year ago I didn't think this) Caratini, Bote, and Hoerner in some kind of roles.
