Likely, January is mostly IFA signings
One item to watch is the Dodgers / Bauer situation. Apparently the Dodgers haven't been that active this offseason, not because of Ohtani, because they don't know if they are on the hook for $40M or not.
With all the high end FA signed, if the arbitrator rules in MLB/Dodgers favour, we probably see the Dodgers making trades and taking on contracts.
