Absolutely agree, but it's not like the WCO and the coryell are the only two offenses in the NFL.
I, personally, would like to see Cam in an offense very similar to the Texans' offense. Zone, stretch runs, naked bootlegs by Cam, 20 yd passes to the TE over the middle, etc. Being able to get Cam into open space, while having targets in the short yardage, the middle zone, and deep, would be great.
There are variations, but those are the most common systems.
But yeah, there are others. 49ers are running a modified version of the pistol from what I understand. The guy who created the pistol, Chris Ault, wants to coach in the NFL.
Wont surprise me if he gets an OC job somewhere (doubt it's with us though)
