Kosi might not be Simple Jack, but that offense last year had the playcalling done by Simple Richt. I get what Richt was trying to do - run proven plays at a high level of execution, keep the system and the reads simple, and hope our guys won all of their one-on-one matchups. Against a lot of teams, we could do that. Play anyone with similar athletes or just better coached ones - we struggled mightily.
Enos is going to put whoever the QB ends up being in the best position to succeed. It's not going to be one-read and then hope something breaks open. It's not going to be us running the same thing on every 3rd down and opposing defenses sitting on it and daring us to make the play work somehow. You're probably going to see levels concepts out of Enos off of playaction, you'll see crossing routes, you'll see actual route combinations that work, you'll see motion to help the QB and the rest of our offensive personnel identify coverages and where the weakness of the defense is going to be on that play.
It got to the point with Richt where defenses sat on what they knew we were going to do with our simplified offensive concepts/playcalling. While simple helps you learn it and hopefully execute at a high level (Richt's intent), it also gives opposing defenses and coaching staffs a leg up by knowing tendencies and coaching their guys on what's coming. Even with us having better athletes at most skill positions, it made it easier to stop for the UVAs/Wiskys/GTs of the world.
Basically - Enos' system is more complicated, yes. It puts more responsibility on the QB and every skill position to learn more complicated offensive jargon and plays. However - it gives us options to dictate to the defense what we want to do in terms of isolating favorable matchups as opposed to defenses just sitting on the simple stuff they've seen on tape. Predictable versus unpredictable. One option versus multiple options. Richt wanted to out-athlete every opposing defense. Enos wants us to out-scheme AND out-athlete every opposing defense - it just makes life so much easier on the QB and the offense as a whole when you take that approach.
