This does feel a little like the 2017 off season, where the team was coming off incredible SP health and a playoff appearance in 2016, and then proceeded to jump the market early (Morales, Pearce) only to see the market crater shortly after. Hell, they even signed a Cuban with no MLB experience that winter (Gurriel). It certainly looks like they jumped the gun with the KK and IKF signings. KK had little to no market based on his own words, and IKF is a 80 wRC+ player so even with the defense I don't see how that's the type of player you overpay and jump the market on. Turner is a bit more justifiable, but out of all the DH options, he was one of the least appealing to me due to age. Of course, the FA market was so bad that the only real difference between what they did and what they could have done by waiting is probably a marginal difference in wins. Only real difference would be in payroll, which would have some significance if it opened up a bit more room to add a Chapman type on a short term deal without having to worry as much about the CBT implications, but I think the FO is truly done with Chapman and don't care to bring him back.
Honestly, the more I look at this team, the more I hope they say f*** it and just put Orelvis at 2B and Roden or Schneider in LF to begin the year and let whatever happens happen.
