I've noticed that some rookies numbers jump up after the first few pre-season games. I have a question on this.

Let's say you have a rookie QB and he is a positive growth player. Does it matter if he has a good or bad performance in the first few pre-season games? What I mean is will the amount his numbers jump up depend on how good or bad he plays during the first few pre-season games?

You'll notice a player's potential will improve, decline or stay the same during his first training camp. After that point, the potential ratings will only follow the same trend (i.e. if he goes down in first camp, he will continue to go down or stay flat in subsequent camps).

As far as the active ratings, players can only improve those. So if you're rookie QB has an active accuracy of 60 and a potential of 80, he will close the gap as he continues to develop. He may not ever improve, but he won't get worse, no matter how badly he plays.

So you are saying the active rating growth does depend on their in-game performance and the potential rating simply follows the same initial boom or bust pattern from their first training camp?

Active rating growth depends on playing time, but not performance. Unclear whether coaching makes a measurable difference. Correct on potential rating.

In essence, the more you play a player, the faster he will progress towards his potential.

QBs are a whole different animal

I have had QBs with 90 potential and 100 pass accuracy potential that after their first camp had a 40ish current pass accuaracy.

It can take seasons for them to reach their potential but the more you play them the better. The problem is a low pass accuracy QB will really struggle until it approaches 60. So you have to weight the potential of a young QB versus the overall quality of the team. In some cases, letting a great potential QB sit and learn is best while other times it's better to play him and let the team takes its lumps.

Some active ratings, if I remember right, are tied to position experience. So once a player is at full position experience, you'll see those position attributes start going up.
