They would need to make sure he'll be 100% and ready to go in Spring Training. If so, they should call Cleveland and make a deal for Corey Kluber. Hal will love him. 2 years left on his deal at 17.5/18 million, each year with a 1 million buy-out. Package something around Frazier and German.
Doubt any team is going to trade for German when he is probably looking at a suspension ...Osuna was suspended for 75 games...if the PA is not appealing then its probably going to be a very long time before German pitches and even then once he is allowed it will take weeks to build up the arm strength. Then again the Stros did trade for him during the suspension...
