From what I have heard and read from a bunch of different sources, it doesn't matter how much money the Seattle group has, because it's not an auction. People (especially in Seattle) just don't understand that. As Stern has said, it's not a question of economics. The question is whether the BoG is willing to approve the sale of the team to a group that's going to move the team to Seattle
in spite of the fact that there is now a local group willing to buy the team and keep it here.
It's not as simple as "well, Ballmer and Hansen have more money, so they win." It's way more complicated than that, luckily.
It's also not as simple as saying "but they already paid $30M to guarantee everything." There are lots of ways of handling that, including the Mastrov group paying the Hansen group back for that. It's kind of debatable in my mind whether that mattered anyway, since it wasn't the Maloofs or the Hansen group that was going to decide whether the team could relocate.
The other one that people seem to focus on is that the Seattle group has submitted an offer to the Maloofs that has been signed. That fact also doesn't mean much...if the BoG says "wait a minute," then things will change.
