The few bright spots:
Jimenez is as good as advertised
Cease was able to increase his innings, dominate, and stay off the DL
Luis Gonzalez and Luis Basabe look like decent prospects
Lopez looks, at the very least, like a decent back end of the rotation starter, with the potential to be a mid-rotation guy.
Palka looks like he could be something. What, I don't know.
All of the crap that happened this year:
Kopech TJS
Burger lost a year and a half of development time to injuries
Hansen got injured and looks more like his senior season at OU rather than the guy who led the minors in strikeouts in 2017
Dunning had an elbow injury that has a non-zero chance to end with TJS in ST 2019
Robert missed the majority of the season with injuries, and hit 0 HR in 6 weeks of game action
Rutherford still doesn't have any power
They spent the 4th overall pick on Madrigal, who might be nothing more than a glorified singles hitter
Zack Collins isn't a catcher, which probably makes him a fringe prospect at best. Not good for a 10th pick overall.
Zack Burdi came back from TJS throwing 93-95 instead of hovering around triple digits. Not good for his future prospects to be an MLB pitcher
Giolito looks like a bust at this point...I had really high hopes for him this season, but at some point you have to call a spade a spade
Moncada is a huge question mark at best, and could be on his way to joining Giolito in the bust category. The same comment about Giolito could be said here.
Avi looked more like the 2016 version
Abreu had the worst season of his career
For the majority of the season James Shields was the Sox best starter.
All of the minor league bullpen arms that looked promising came up and got torched. (Hamiliton, Burr, Vieira)
At this point, 2020 looks like a pipedream at best, and while it is too early to write the whole thing off as a failure, if things stay the same in 2019 you seriously have to consider an organizational housecleaning.
In conclusion, it seems like in the most likely scenario we end up right back where we were in 2016 with about 4-5 decent players and a bunch of crap, maxing out at 75-78 wins, but without the benefit of the great contracts that made this "talent" acquirable. I don't think the Cubs or Astros minor league talent as a whole ever looked this questionable. We all thought we were going to see the golden age of White Sox baseball coming up. Now it looks horrible. They're losing around 100 games with no end in sight.
