2016 we had the benefit of two NFL players on offense, who won nine games despite a really crappy offensive scheme.
In 2017 we took a huge nose dive. The less said about 2017, the better.
In 2018 Kalani fired Ty Detmer, brought in Jeff Grimes and a bunch of other offensive coaches, and BYU crawled out of the pit.
Watching the team improve last year after 2017 was very satisfying.
