I've been trying to think of ways to combine Arizona's 3 QBs, and I haven't been able to come up with anything that would be very beneficial. Obviously subbing them in and out doesn't work. Surgically grafting them together doesn't seem like it would have much advantage, although if you put two on the bottom and one on the top, he'd be really tall - but probably slow and he'd just be throwing from farther away. Having 3 on the field at once would help a bit since two could block, but I doubt any of them are decent blockers and it would mostly just offer an illusion of protection. And they'd still suck at throwing the ball. I've either under- or over-thought this. Probably the latter.
