Which one is more important?

I shall do the same question...but i think about it and i realized the most important is number 2,"Best rating\best potential rating",of course,for a specific role.

If you see a team,when you press "best 5 teams",the program choose the players that have the high level for that position.Don't think is a coincidence.And maybe the RATING is the result of attributes and current ability.

Regards.
