Kalani Sitake took steps to address last year’s disappointing 4-9 record — the worst at BYU since 1970. The main culprit in last season’s slide was an offense that averaged just 17.1 points per game. Veteran offensive line coach Jeff Grimes — most recently at LSU — was hired to call plays for the first time in his career, and he’s one of five new offensive assistants in Provo. In addition to the scheme and coordinator change, BYU faces uncertainty at quarterback. Tanner Mangum is recovering from an Achilles injury suffered in 2017 and will be pushed by Beau Hoge and Joe Critchlow. The defense returns seven starters and is the strength of this team once again. With four games against Power 5 opponents, along with a trip to Boise State, BYU faces a difficult path to bowl eligibility.
