Offensive prowess as measured by points per game. Someone smarter than me can find an opponent-adjusted metric for offensive performance or efficiency. I'm including information back to the 2018 season, and while ARod was not the OC for those two Grimes years, he was the QB coach and passing game coordinator. "NFL guys" is defined as playing in an NFL game, although some of these names were borderline as practice squadders.
Of the eleven offensive positions, I'm highlighting QB, RB, LT and WR as key positions (although a pass-catching TE like Matt Bushman kind of deserves to be there too).
2018 — National scoring/game rank: 79
Key positions: TMangum and freshman ZWilson splitting time at QB, Soph BChristensen at LT, MBushman at TE with just over two catches/game that year, no future NFL at WR or RB.
2019 — National scoring/game rank: 68
QB: Soph ZWilson, Bushman at TE, BChristensen at LT and BFreeman starting seven games at the RT spot, three and a half games out of Ty'Son Williams at RB
2020 — National scoring/game rank: 3
ZWilson at QB, Christensen and Freeland at the tackles, DMilne at WR, and TAllgeier at RB.
2021 — National scoring/game rank: 28
JHall at QB, Freeland LT, Puka at WR (when healthy), and TAllgeier RB
2022 — National scoring/game rank: 44
JHall QB, Freeland LT, Puka when available at WR, Chris Brooks RB when available
2023 — National scoring/game rank: 102
Kingsley at LT when available, KSlovis and ARobbins noted here but played partial seasons for BYU and have only played preseason or practice squad NFL snaps
So, the secret to successful playcalling is easier said than done. Just have NFL talent, preferably as upperclassmen, at all four key positions. Unfortunately, I haven't seen much NFL draft chatter about our current offensive roster.
Certainly, coaches play a role in developing the players into NFL prospects. I assume there are multiple coaches involved with any player's recruitment and development, as well as collaborative play calling.
Just some data on Jimmies, Joes, Xs and Os.
