Yea but he was able to have the same production at Missouri. The fact that he has proven he can run his offense in this conference is enough proof to cancel that out. The fact that he is coming back to something rather than coming to something new should help him a lot.
Not when he was OC in 2016 they didn't
In 2017 Missouri's offense only put up numbers on bad teams, similar to what he was doing at UCF
In 2017 Missouri didn't beat a team with a winning record:
Missouri State 3-9
Idaho 4-8
Uconn 3-9
Florida 4-8
Tennessee 4-8
Vanderbilt 5-7
Arkansas 4-8
It's been the same story each season, Heupel's offense puts up big numbers against bad teams.
Dooley came into Missouri in 2018, and did more with Drew Lock and the Missouri offense, than Heupel did in 2017.
