Balanced from the run/pass standpoint? Doubtful. Gus essentially runs a very modernized wishbone - run option offense; multiple run options. The pass is the last option on the vast majority of plays.
If Johnson develops into a good downfield passer, like it appears he will, Gus will use that to his advantage. I doubt it will be 50-50 but if Auburn had thrown the ball 5-6 more times per game this season and done so effectively they would have been much more difficult to stop.
Designed to keep the D honest and hopefully catch someone off-guard, like in the Iron Bowl with Auburn's last offensive touchdown. As an aside, on that play, clearly Marshall was over the line (it's not the ball, it's any part of the body) and if we are to believe he was not, then the entire offensive line was illegally downfield, which BTW happens constantly but is never called. Do you really think Gus will intentionally focus on a balanced attack with passing? Somehow I doubt it. It defeats his purpose. Plus how do you recruit QBs with true passing skills AND highly skilled WRs when they know they will rarely see the ball? His offense is predicated on creating chaos. Hurry up to the line, snap the ball before the defense can get set, generate panic. the kids on the field start to lose discipline and try to make plays on their own. The offense then simply picks the open spot. LSU did the best job of staying calm and not panicing - they are also masters at faking injuries to slow things down. Can't say that I blame them, when faced with chaotic street ball. Now I could see a possible foray into a run and shoot type deal, but that would be a step backward. That has been figured out and the model exists. I'd like to start a new paragraph here, but as usual, it won't let me use the "enter" button to start a new line, so let's pretend I did.
To your other two points, I don't think anyone dominates for a decade. You are on your second trip to the BCSCG in four seasons. An excellent accomplishment, but last year was a train wreck. You got a lot of lucky bounces this year, but you won't surprise anyone next year. Lastly, I don't think your assessment of Gus is correct, though time will bear it out. I think he is quite full of himself - especially with this meteoric rise. What happens when SEC defensive coordinators figure out the remedy just as they did the wishbone back in the day and Meyer more recently. Gimmick offenses eventually get figured out and straight up tough football wins out. What kind of offense does Gus run then? Will he even still be at Auburn? How do you get a dominating defense that practices against your own option offense all the time? A lot has to fall into place to dominate for a decade. Usually, gimmicks are not enduring.
I didn't mean we would dominate for a decade, I think those days are long gone in the SEC. I think a team, such as Alabama, can dominate for a recruiting cycle and a half or so, but not for an entire decade. If, however, we win a couple of national championships in the next 10 years I would say it was "our decade."
Gus's offense is a classic smash mouth running game with a lot of modern pre-snap motion. It is far from gimmicky, although it does use gimmicks. It is predicated on getting kids out of position. That's the future of football until colleges have more than 20 hours to spend with their defensive players each week.
As for Gus the person, we'll have to agree to disagree on how sincere he is. I suspect you would hate Jesus if he returned as an Auburn fan.
I will ask you though if you don't think Saban is full of himself, or Meyer, or Bryant, or Spurrier, or Parcells, or Belicheck, or Paterno, or Walsh. Or for that matter Clinton, or Reagan, or Nixon, or Kennedy, or Obama. Or for that matter Trump, or Buffet, or Jobs, or Gates.
Great men almost always have great egos. It's what drives them. I doubt Gus will ever go ballistic at a female staffer over an insignificant mistake like Saban (or Bobby Knight) has. I doubt Gus will walk past people asking for autographs without acknowledging them like Saban (or Belicheck or Mike Ditka) frequently does. They aren't shitty people necessarily they just aren't friendly people. (Ditka is a shitty person.)
I've met, and spoken with, a lot of successful head coaches. More than probably anyone else on this board. I've met Gus once, he seemed like the real deal to me. For the record Chizik did too until I met him. He was a fake. He also had that reputation in the press box. Everyone raved about Malzahn though. Stallings is one of the kindest most genuine head coaches I've ever met. DuBose was a POS. Terry Bowden was an ass at Auburn. I spoke to him right before he got hired at UNA and he had mellowed quite a bit. Bobby Knight is a personal hero of mine in many ways and he's an absolute maniac in person.
