I'm assuming it runs like any other fantasy football, ie starting just before the first game of the weekend, and ending after the last game of the weekend, ie monday night football. Once that game is ended you can start putting in your changes for week 2. May be slightly different, but I'll be working to that theory unless I'm advised otherwise.

And anyway, one more sleep till it's time for fooooooootbawwwwwwl!
