So looking at next years cap numbers. Assuming the salary cap projection of $166 million holds up.
If Detroit renounces all of their free agents except Duren they will have $15.5 million in cap space. Which means they will basically have no cap space, since the MLE will be between $15 and $16 million.
So they will have the MLE + the BAE which will be $5.5 million, maybe six.
