I have focused the use of scout before, it requires constant flow of green packs to maintain a great shape
scout player is a slow/medium trainer cause of his age and high Q, so about +30 to +40 are the prices of training in 3 bars/practice,
meaning about 10 of those trainings to gather 3 sp (which is almost nothing) with a great danger for an injury - not so good idea.


I believe there is a "teamwork" value in each player that start low for every newcomer, which increases when played and trained with other players in the same team, to become a constant performer it needs to be developed through time or the use of green packs, it explains why full-team cardio (every uninjured player in the team must participate) is so effective for boosting form on all players.
now you 're getting closer to the sphere of fantasy. Even if this thing exist, I can't imagine how someone can observe this
