ehhhh. They're not ND in terms of numbers, but in their defense-Hmm, tell me more about how BYU is a national brand and basically Mormon Notre Dame.
Week 2 was at 9:30pm central on ESPN vs Stanford. They got 1M people to watch that drek when they should have been in bed.
Week 4 was 6:30pm central on ESPN2, and was up against:
Indy/Ill on NBC
Mia/Fla on ABC
Apple Cup on CBS
Bay/ASU on Fox
On a 2nd tier outlet up against all that is pretty decent - same as ISU vs ArkSt on ESPN2 who was up against lesser tv competition. And they weren't/aren't ranked, which still matters too.
