I don't think you want to throw a contract at the first coach that impresses you. They probably gave Green a response date - most likely this Sunday or Monday, after interviewing everyone else.
Think if they throw a contract at Green tomorrow but today he is at a press conference wearing brick red and saying how impressed he is with Snyder and the Redskins, etc etc. Then we feel stupid and have played our options too early - very unlike Graves.
Now imagine Fassel is here Saturday and he is more impressive than Green and really wants to coach here more than anywhere else. Now you have time to get on the horn with both Green and Fassel, you know what they want to coach, you know what assistants they are interested in bringing on board and you know how they handled the other teams they interviewed with this last week. Then you strike quickly and both the team and future coach get to decide with little regret.
Dammit, ajcardfan, don't you do any gambling
