Each year I make my own spreadsheet with the full NFL schedule that has spaces for making predictions. You can modify it however you wish. There is a line to add the line before the game in question as well.
Several people have asked for it the last two years, so just IM me again with an email to send it to you.
It is an .xls file compatible with Quattro Pro and Excel versions beyond the year 2000.
I use it to make my season predictions and compare my in-season results.
It seems random so far with me winning about 15 more times in 2010 with knowledge each week as well as me losing about 10 more times last year with weekly information.
