An higher level of skill will grow more slowly than lower
Next season will probably be the first time since season 3 that my NT does not have a player trained by me, so I have been well aware of that for the past 30 seasons (I'm sure hudrey is well aware of that as well, he's been here for a very long time as far as I remember)
Yes, I had players popping at 3 weeks before. But he was 27, and his OD was 17. Same level of coach and similar skillset as the one above. Which makes me curious to why a 22 year old who is still far from his potential pop at such an irregular speed.
You know that an important role is the player's height. What is the height of both players?
