It is a myth.
Doogs love to say he helped build SC's offense which is a total joke. He did nothing there and was only the OC for two years and the offense peaked when they kicked out Chow.
In 4 years he's had one good offense and it was only good because the bar wasn't high and because of, dare I say it, Ty's recruits....Polk, Kearse, Aguilar, and Kelemete who protected Price's blindside. It was talent and had nothing to do with coaching.
Wilcox looks at what he has and fits it to something appropriate. Sark tries to run a video game offense no matter who he has.
The fact is, if Sark was actually the OC (which he is) and not the HC....he's get fired by the HC.
