a couple noobie questions...
1) does playing time effect how quickly a player reaches his full potential?
2) Does playing time have any effect on a players max potential number?
3) When does weight gain or loss take place? Is it in training camp or throughout the year?
Thank you!!!

1. Playing time definitely affects position experience at a faster rate (which I believe has some sort of hidden weight in a player's overall rating). I also think that playing time does quicken a player's reaching of his potential. But some players will develop slower than others. There must be some sort of hidden thing about a player's development rate.

2. I have only seen this affect a players max potential number when I have changed a player to a new position. This is why I believe that position experience has some sort of affect on a player's ratings, even though it has no spot when you edit player's weights (for your own personal ratings, not how heavy they are)

3. Speaking of how heavy they are... a players weight will begin to change on the next sim after you change their position. I believe that Training Camp gives them a much bigger jump or drop to the weight for their assigned position, but during the season it takes a couple of game weeks to get a player to the right weight.

I don't have all the answers, I'm sure, but hope this helps!

Attributes, position experience, and play knowledge are completely separate concepts. Attribute growth is fixed per player and linear. Position experience and play knowledge increase with snaps.

Not sure how much PE or PK affect non-QBs. My guess is not much.

Thanks guys very helpful! So as a follow up is position experience gained at the position he is labeled as? Or the actual position he is taking snaps at? For example if I have a WR taking snaps at RB, does he gain experience and improve his rating as WR or RB?

Both. The position the player is listed at is the "practice" position. Players also gain PE per game snap.
