offense. You'll see a little different emphasis in play-calling but the overall scheme will be very similar. Through all the OC changes Utah has steadily been more competitive in the Pac-12 offensively; why would that change this time with an OC that's been coaching P5 football for most of the decade? Over the last 2 years Utah has been one of the best teams in the conference in big plays, moving the chains, and the red zone. And almost all of that production comes back.
It's worth noting that over the last 8 regular season games Utah went 7-1 and averaged 35 ppg.
I'm not saying Utah is going to average 40 ppg, but it's reasonable to expect that they'll improve overall.
For whatever reason BYU fans on CB are weird about new OCs, as if every OC is installing an NFL air raid system to a team full of guys that have never played football before.
