Pitching Log Jam

I generally think the Cubs addressed most of their problems at the trade deadline. Inadvertently, however, they seem to have created a new set. The Cubs have three players due to come off the DL in August. Obviously Bote will spend a couple of weeks at AAA when Bryant is healed.  What to do about Morrow and Darvish?  Only Duensing is pitching badly enough to get cut and he is signed through 2019. It will be interesting to see how Theo and Jed manage this one.
