Coaching is a lot of it, but also college level schemes and competition can make QB's look better than they are. At the NFL level they have to be able to read D's comprehensively and go beyond single read or option schemes. Just look at that video of Stroud breaking down his pre-snap reads and you realise how much football smarts the kid has. It's teh same reason the like of Brady, Cousins and Purdy belied their draft position. Their physical attributes are just one half of the puzzle. Their brain is the other. And bad coaching can mess up the latter just as easily as physical injury can mess up the former.
