The season is finally under way. We have had a chance to watch teams play against unfriendly opposition for the first time, and some teams were more impressive than others, but for the most part, you should guard against overreacting to the first week's results.
I have always felt that as long as a team gets the win it should, first week struggles don't really mean much unless the continue. One week is not a trend.
That said, some results cannot be overlooked.
Wisconsin also dropped out of a committee game after blowing a big lead and losing to LSU. That loss wasn't unexpected, but the Badgers now have some injury concerns in their young defense that could cause problems down the road.
Otherwise, there are not many signficant changes as there were few upsets. One change of note is that Northwestern had previously been projected to a bowl as a 5-7 team. The Wildcats' loss to Cal over the weekend though changed that, and the Air Force has taken their place.
