Well, that's only kinda true. When Stoops was hired he mentioned Oklahoma State as an offense he would like to emulate. OSU "claims" (we will address this in a sec) to run the Air Raid offense. Couch suggested Brown, but it's not like Stoops was against the hire. Stoops took this job with the premise that he could hire his own staff.....any coach does.
The Air Raid has morphed. Clearly very, very few people run the actual Air Raid anymore. However, many still claim that they do. Brown, Riley, Holgorson, etc, all claim to run it but many of them only throw it 55-60% of the time. They really just run a fairly balanced spread.
Holgorson was one of the main architects of the offense that OSU employs. So, there was a connection with Dawson here. I just didn't like it because he was inexperienced and didn't call the plays. As far as philosophical differences between Dawson and Stoops, I know that Stoops hated being at the goal line in shotgun and running 3 draws to Boom (who shouldn't have been in the game) until time for a FG......things like that. And I know what offense Stoops has said that he admires.....so the philosophical difference was likely more related to situations like above.
Gran would be fantastic. He literally would check every single box to the positive. I just hope it comes to pass.
