Cot's actually has us less than a million over the CBT threshold.
Remember they had a placeholder of the $700K minimum in each roster spot, so while we mentally add $20 million for Castellanos the actual CBT increase is only $19.3 million.
Now we will need $3-$5 million more for IL moves (JoJo Romero will make the $700K minimum most likely off the roster for instance), but we are actually not that far over. If we are done adding, there are actually many paths to get back under later in the year if the team is not doing well. And lots of room to the next threshold. Correa would have put us close to that threshold, but still about $4 million under.
