I hate to be that guy, but I guess since Donkey has died, I will be.
This whole Napier offense question is nonsense. Unless you are Navy or Army, almost everyone has the same offense, to include the NFL. What separates them is the play calling.
Not many are lining up under center anymore. You can do the same stuff from the gun and do it better.
Everyone is running power, counter, inside zone, outside zone. Add in left and right and you have 8 running plays. Add in the QB power and counter, and you have 12 running plays. Like the option, OK, there is 14 running plays. Throw in a reverse, 16 plays. Not a whole lot else you can do.
There are only 9 routes a DB has to account for. LBs have the drag route, YoYo (some call it Q) route, the RB swing pass, or the RB post (stick post).
Spurrier's O was a lot under center, then went to the gun. Same routes, different combinations.
There is literally nothing that Alabama runs that Clemson, OSU, or UF doesn't run. The playcaller is what is different.
So, our offense will not change, but the play calling will. We may run from the pistol a little more, or the spread. I like the way Napier starts in the pistol, let the D get set, and then shift to the spread and run to the side where the DTs are lined up to give you the advantage.
We will run post and corner routes, ins and outs, slants and gos, fades and digs and EJs favorite, the hitch/curl. That is the 9 routes mentioned above. Drags, yoyos, and over routes are typically safety and lb routes. Not much you can run unless you put a special twist on how you run a particular route or set up a defender.
It may look different, but we will have the same plays as everyone else.
As far as what Napier calls, it will be up to the personnel and match ups on the field.
