Reading into some of Lisa's tweets from last year and listening to some of Zach's interviews this year, it's pretty apparent there was a time last year when they weren't too happy with the reaction of the fan base to some of Zach's struggles. He alluded to it in one of his interviews earlier this season. I imagine he's loving BYU right now but there was a period that BYU wasn't loving him last year and they took notice.
