Siemian is a very smart man, but it's not like his grasp of our "complicated" offense helped him succeed. I don't care much how simple or complicated an offense is if it works - this offense was basically terrible. If they're even talking about taking a QB who was just on IR because of injuries and running a read-option with him, though, then the Broncos really are staffed with idiots. Maybe they meant RPO.
I would settle for a "two-progression, then run and slide" offense at this point.
