NFL/NBA now have a Donald Sterling problem with Gayle Benson

I know this should probably be a side-bar discussion, but I've heard this suggested before that if Gayle is not allowed to take over the team it doesn't mean that Rita will inherit it.

If that is the case then what happens to the team? Does the NFL essentially put it on the open market?

If someone is the rightful financial owner yet the NFL rejects them, they can force the sale of the team I think. But they can't take the financial rights away from Gayle and they can't force her to sell under market to a specific person.
