@Edgysam Kicks Butt on Weeknights - Why?

Over the years, @Edgysam and the College Edge have had a lot of success handicapping the weeknight FBS schedule. Over those same years, I've tried to figure out why. One of the reasons was the simple fact the weeknight schedule includes only one or two games. It's nice to narrow your focus on only two to four teams.
My picks over this past weekend have opened my handicapping eyes to a more important reason why I do a pretty good job on weeknight games. I also think this sort of revelation will help me with weekend games as well.
I lost two picks this past weekend where the teams I selected were the much higher rated teams under my College Edge ratings: Virginia Tech and USC. The problem in both games, a problem I acknowledged, was both teams were coming off of gigantic wins the prior week: the Hokies over Ohio St.; the Trojans over Stanford. Any rational handicapper had to look at these two sides and seriously consider there might be a  letdown. I thought the ratings edges would overcome the letdown possibilities. I was wrong.
So, how did those two bad losses open my eyes to my Thursday successes and possibly help me in my future handicapping?
Weeknight games on ESPN or FoxSports are the highlight games of that night. Those college kids are the focal point of the entire nation. In some cases(like last week's game between LaTech and North Texas), it might be one of the only times any of these players will ever experience that kind of exposure.
The chances of a letdown on this national stage are far less likely than they would be on a schedule-crowded Saturday. In my opinion, the College Edge ratings I've developed over the years are more likely to hold true on weeknights. Letdowns are less likely to have an effect on those games.
On crowded weekend schedules, I have always considered intangibles like the letdown possibility, Henceforth, I need to give that even more consideration.
