Although next winter lacks some potential impact players the Sox might find useful outside of the shortstop position. Even with Bogaerts opt out, the Sox are better off extending him over pursuing the bigger names at that postion for a cuple reasons. Like signing Correa/Story and trying to trade Bogaerts seems counterproductive, since Bogaerts trade value for only one potential year of control while Correa, Story, Seager and possibly Lindor (unless the Mets extend him) are all available seems like poor timing. If you look at what the Guardians got for Lindor (and Correa), it's not exactly a game changing package. And Bogaerts is not likely to be worth more.
The pitching available next seasons isn't as impressive, either. There is no equivalent to Trevor Bauer equivalent unless Bauer himself opts out (which is certainly possible). The bigger names are all getting up thee in years, with Kershaw (34) and Scherzer (37) looking well into their post-prime years. Lance McCullers might be the most intriguing name, but he is not exactly the most reliable arm. And pitching will be their biggest need, like it will be for most teams.
Are there any outfielders comparable to even Springer? Most of the better ones will be in their mid to late 30's and any deal will have questions from the onset. The best outfielders under 32 might be Schwarber, Pederson, Rosario and Castellanos. And three of them were available this off-season via free agency (and all got one year deals) and the 4th was an easy trade acquisition from a salary dumping team, and still had no takers...
