Field vision, fast post snap processing speed (Able to go through progressions quickly), anticipation, pocket presence & mobility, ability to throw under pressure/getting hit & atleast good accuracy/ball placement.

I dont think any of those traits are teachable either really. You either got it or you dont.

Gotta be able to read defenses pre snap eventually & I do think that's teachable.

A really strong arm & a quick release aren't a necessity but they really do help as we see. Mobility to get out of the pocket and/or run is also helpful but also not a necessity as we've seen with countless pocket QBs.

And obviously durability, intelligence, work ethic, leadership skills & the desire to be great are a must.
