I don't think the Sac group has to catch up as much as you think. KJ has been anticipating this move by the Maloofs for quite a while. All the parties involved know what needs to be done to present a valid counteroffer. Remember KJ going to the BOG with not just $10 million but ALSo Burkle in the back pocket? He knows just meeting the minimum isn't going to cut it. He will have an offer that more than matches the Maloof share and also have a signed agreement that if the local group keeps the team they will agree to the previously-agreed to deal with the City for a new arena.
Remember that AEG was also asked by Stern to "re-engage" and affirm that they are still in for the deal as well. Remember that Stern was torqued at how MSE turned down the deal he personally negotiated on their behalf (at their request!). Remember that KJ and Stern are in constant communication and from what I can gather, KJ feels someehat optimistic on our chances. So don't give up hope yet. MSE was shot down before and they (fingers crossed!) will suffer the same fate this time as well.
