2009: Schramm promoted to OC, Alford moved from Corners to RB’s, Blake Miller hired for O Line
2011: Chow hired as OC, brought Tim Davis to coach O line after Miller left. Schramm/Arod reassigned
2012: Johnson promoted to OC. Dan Finn O Line. Hill moved to RB’s. Tuiaki hired for FB’s/TE’s
2013: Erickson brought in as co-OC. Tuiaki to D Line, Hill back to TE’s
2014: Christensen brought in as OC. Harding hired for O Line. Stubblefield hired for WR’s
2015: Arod/Harding co-OC’s. Freddie W hired for TE’s. Holliday hired for WR’s
2016: no changes
2017: Taylor hired as OC. Brought McDonald with him to coach RB’s.
2018: no changes
2019: Ludwig brought back. No other changes
Based on the above, I can’t see any time that a new OC brought in his own people other than Taylor and he got 1. Everyone else was a Whitt hire and that’s the biggest reason Utah’s offensive philosophy hasn’t changed in the last 2 decades.
