Looking at a couple of computer rankings like Massey, Sagarin, and SP+, Utah’s strength of schedule is middle of the pack compared with the rest of top ten.
Utah doesn’t have a signature win, but overall their SOS is within reason and certainly better than even teams ranked above them. Utah has just played a bunch of teams hovering around .500. No Arkansas or Rutgers in conference play.
This is what make college footbal interesting, but also annoying. Quality losses, quality wins. What other sport is ever talked about in those terms?
