With Fever, I think they have done ok with the Jenner signing. In my opinion they need a GD/GKas much as they need a WD.
Realistically Ellis isn’t an option, even if it is to bring Bruce forward, she just isn’t effective. Fever have a couple of quality TPs that can cover the WD/C, and they have stop gaps if the change is needed during the game. They could even try Ellis in WD for impact.
