Been taking a look at the transfers lists and it seems to me that the player’s main feature (regarding their position in the field) is not very different from other main feature number.
For example, a youth defender has between 55 and 60 in tackling, but also has the same range of numbers in passing or shooting.
I think that the main feature should be a little bit higher that the other two main features.

Looking at the code here…main skills are designed to be higher than secondaries, in general, but I see what you’re saying. Maybe we’re looking to biased players :-)

I got a defender in Beta 2 which has 71 passing( a real star midfielder for my team :)) ) and 63 tackling. I put him as DM
