"I don't think lack of viewership is the reason for lack of dirty reputation (especially since if, as you suppose, they're all opponent fans they would be more attuned to notice that)."
Just that the data indicates that lack of viewership is not the reason for Utah's lack of reputation as a dirty team.
That said, I do think it will be interested this season with BYU having so many PAC12 opponents to be able to provide a better comparison of BYU vs Utah drawing power against similar opponents.
