More about the QB battle from the link Rivals sports link...
In particular, the ability to translate what’s been coached in the meeting room onto the field when the spotlight shines the brightest could end up being judged as much as anything.
“Just to understand this: (a QB) may know what he's doing, but if he doesn't understand the mechanics that are involved in doing that, he's going to be dead in the water, flipping around…" Verduzco said. "A young guy can score really well on a test, but then he gets on the field and it's like, ‘What are you doing?’ That happens for a variety of reasons.
“Sometimes that's correctable, and sometimes it's not. What ends up happening, those guys go into, let's say spring ball or fall camp like this and then when the bullets start flying and scrimmages and what not, or seven on seven - you understand the point?
“That confidence part of it, that's another fascinating conversation and topic... (NFL) guys talk about that quite a bit, and it's a fascinating thing. What comes first? Performance or the confidence?”
