I refuted #2, but they- being fans of teams with more fans and therefore (in their minds) more in tune with how college athletics are run, assured me that the two Red River Rivals (and possibly "7 or 8" of the Big 12 teams) would never step foot in the new Amon Carter Stadium.
Luckily, Patterson stepped in to throw cold water on this theory yesterday:
"We built our stadium to play in it. If we play in Cowboys Stadium now it'll be for a non-conference game. We built our stadium to have purple in it"
