What on the world is going on, never seen a decent question that actually makes sens from a guy that's new to the forum.. and also new to the game ?
People here that been playing for more than 2 years got no clue what you talking aboutincluding myself hahaha
This is something that we see on the new 2016 version and it's interesting to find more about it..
Whenever a DC gains a new position such as DL or DR the engine recognizes it as flank player and automaticlly unlocks the Speed & Crossing ability as those are key ability for any flank player.
The engine unlocks those new ability skills for the automatic skill point distribution after a game.
This means that once you unlock the new position the engine will start distribuiting skill points to the new key abilities after every game.
It's different in training sessions as you have control over the drills and the ability you want to teach to your players
It's also a sugestion, helps you to train your player in more efficent way by using the exact drills that will help your player increase the key abilities.
