Last year in USU's 5 non conference games they averaged 180 rushing yards and 229 passing yards per game.
On the road (8 games I believe) they had about 182 rushing yards per game and 240ish passing per game.
They supposedly played a ranked team during the regular season although at a quick glance from the mediocre teams I can't even tell you which one that might have been. With that being said against the one mystery ranked opponent they had 118 rushing yards and 164 passing yards for a total of 282 yards.
I don't think they get more than 250 yards and thats if they play their best.
Tennessee at home last year:
Average rush yards against : 171
Average pass yards against: 150
