Eh...I think "ducking" is a bit of a strong term here.
I totally understand the hesistency of a school to get involved in something that isn't a home & home. It sounds to me just from this excerpt, that if Wisconsin would be willing to travel to Fort Worth the year after Madison, then they could have themselves a game here.
Home & homes are pretty common place with non-conference matchups in college football unless some doormat is willing to go to a Top 25 opponent just for the payday. TCU doesn't seem to fall in that department.
Its ducking considering the rheatoric that TCU boosters have been putting out there the past few years. I don't think TCU itself ever put it out there. I understand their reasoning, but this just highlights than Boise/TCU could get tougher games but choose not to play in them because they want "better terms" for themselves.
True about the booster item
From the school's standpoint, its clearly in their best interests to arrange a home & home with an opponent rather than a one time away game when the program is already Top 25 contending. Schools that tend to do the one-time road game do it as a money grab for their athletic programs. Usually these are the smaller programs out there, the D1-AA schools where the money really means something.
If you're trying to maintain a program or build it exposure, home & home is the way you want to go. Drawing a team like Wisconsion to Fort Worth would be a coup so I understand the school's relucantance here.
However, on the surface, I can totally understand why people would jump to the idea that schools like Boise & TCU would be ducking bigtime programs.
