BYU's offense tends to stall mid-drive. The only reason why we averaged 7.4 yards/play was because we had four 45+ yard passes and a 56 yard rushing TD. Other than that we struggled to consistently get chunk yardage.
It seems to me that A-Rod and co. struggle in hashing together series' of play types that result in short yardage situations. Lots of 2nd or 3rd and longs today. I would assume having no run game plays a large part in that.
