To rephrase the question, it isn't so much about 'NFL-ready' vs. 'Raw', as it is 'NFL-ready' vs. 'Potential'.

 

Obviously, there will be rare QB prospects such as Andrew Luck who was not only NFL ready, but still had a lot of room for growth, because of his immense physical tools. But, for the vast majority of prospects who are hyped up as being a 'day 1 starter', they may be as good as they will ever be. When I hear people talk about Teddy Bridgewater, they say he most valuable trait is his knowledge of the game. That's a good thing to have, but if he already knows as much about football as there is to know, how much better can his game become, before his god-given physical/mental tools limit him.
