If they were REALLY that close to a complete deal- I think that something would be different- a 24 hr extension. 4 hrs- that is not enough time to get something THAT complicated in writing for a final deal. THIS might be a way to give the teams enough warning that this is all they are going to get and get the cuts done. there has been so much delay and talk that some teams might have just decided to sit on their hands and do nothing (Aint's, Cards, etc). This extra 4 hrs is for them to get their acts together.
