Jacob Conover has been in this situation before. Two years ago, he made his collegiate debut in BYU’s 34-20 win over Utah State when quarterback Baylor Romney, filling in for an injured Jaren Hall, was also hurt late in the second quarter. Conover entered the game for the Cougars in the second half and completed 5 of 9 passes for 45 yards as BYU relied on its running attack to lead the team to the victory.
