For kicks I did a quick web search just now to see if anyone had a compilation of all of the rankings/polls. Found this site:

I imported the data into a spreadsheet to compare BYU and Utah. Looks like there are 113 total rankings/polls that include BYU and Utah. 86 currently rank BYU higher than Utah, and 27 rank Utah higher than BYU.
The rankings right now are as of last Saturday's games. Obviously BYU will move up a bit with their win over Boise State. If Utah beats USC they will as well. Interestingly enough, Boise State and USC are very close to the same average ranking (39 for USC, 43 for Boise State).
