I’m not sure I understand what you mean.
A spread offense is nothing more than a 3-5 WR set. That’s it. It doesn’t means QB runs or doesn’t run. It means you spread the defense out, sideline to sideline, with multiple WR’s sets.
So, Sark has definitely run spread offenses before.
Now, the next question is, Huntley is a runner. Does Sark want/know how to run a QB?
Well, the offense that Petersen went to the playoffs with was all Sark players. And the QB’s that Sark recruited to run that offense (before going to USC)?
Tyler Miles and Troy Williams. Both the #2 dual threat guys from their classes.
Sark wanted to run a QB at UW.
He makes perfect sense, to be honest.
He can Urban this job into another Head Coaching job. If he takes the job, he will be a PAC-12 HC in 2-3 years.
