Q: Ira, I keep reading these fantasy trade scenarios online regarding Jimmy Butler. Most of them involve the Heat getting back less salary and draft picks. In the event the Heat might consider trading Jimmy, are there rules that govern how much they must take back for him? – Rich, Plantation. A: The rules under the new apron system are mostly based on not taking back more than is sent out in terms of salary for teams, such as the Heat, that stand above the first tax apron.
