it seems this system would reward teams that have had blowout games. For instance, Green Bay's blowout over the Saints, and Chicago's blowout over Detroit and the Vikes. I think if there was some way to consider point stacking late in the game (teams behave very differently when they're behind - they become one dimensional)... and there'd be more variability early on in the season based on the teams they play. Again, using the terrible NFC north division as an example - the Bears, Lions, and Packers are higher than perhaps they should be because they play in such weak divisions - and have an easier schedule.

...just an idea - but I think this is pretty cool.
