In regards to TCU .. there are a lot of factors in play that are hard to guage.
1. TCU snubbed in favor of a BigTen school so they may want to prove a point beyond just the normal
2. They are really good friends so that could play into not running it up if the opportunity appears

3. TCU statistically and otherwise dominated the game last year more than the final score would indicate. 427-268 last year and won by 30-7 final. It was TCU's season low scoring output.
4. TCU underachieved on the road last year. I know from personal experience that Patterson has struggled covering as road chalk, 3-8 last 11. The road woes are the biggest concern for TCU money.
5. While TCU will be really good defensively eventually this year, I am not sure that is the case week 1 out of the gate.
6. They played last year so it isn't like the two teams are unfamiliar with eachother and what they do. This is a big advantage for dogs in conference play and it could apply here to a lesser degree.
7. There is a huge disparity between QB's. Not just that Boykin is much better than Leidner but he is a much better fit in the TCU offense than Leidner is in the Minnesota offense.
8. TCU offense ended the year firing on all cylinders and with all back, I have to think they outperform last years output against Minnesota.
9. Figuring out who controls pace is a factor. Minnesota one of the fifteen slowest paced teams last year, TCU one of the 30 fastest paced teams last year.
It is a hard game to figure out.
