Agreed, there is variation and modernization that has taken root. As Mario has made abundantly clear: he’s not trying to time travel to bring the past to the present.
I want Fletcher and Pringle on the field together; and Lofton can help clear the way for them. He can also catch outs and curls, too. Likewise with our RBs getting more involved.
Calhoun was Kubiak’s 1st OC in Houston after working with him on the Broncos; then accepted the Air Force job. Davis left after 2022, during the 2022 season, he relinquished offensive line responsibilities while Viti switched over from RBs to offensive line.
He worked under two other offensive coordinators after Davis left: Drew Thatcher and Cody Worley. Sneaky passing concepts as you mentioned; Dawson was a GA, only in 2005, when Thatcher was playing WR for Hal Mumme at New Mexico State.
In 2021, Viti is listed as having been the running backs coach instead of the fullbacks coach for the first time; fullbacks coach for the prior 5 seasons. Titled assistant coach for the offense / offensive line in 2023. He was promoted to associate head coach / OL for the 2025 season.
Previously the TE coach, In 2023 & 2024, Matt Drikall (current Central Michigan head coach) worked the offensive line with Viti.
A lot of overlap between Upshaw, Dawson, and Viti.
