What happened: A trade involving Herbert would have to account for salary-cap costs on both sides. A large contract can be difficult for a new club to absorb or costly for the current club to move.

Why it matters: Jeffery Simmons' contract was structured to be transferable, illustrating how deal terms can matter as much as salary. Those differences limit which proposed trades are financially workable.

What to watch: Any Herbert deal before the deadline would need to satisfy both clubs' cap requirements.
