Here we have a term for them, called "key players", which means that are internally well programmed. As always the visual attributes affect just very slightly to the intgernal ones, but, these are used to, determine the AVQ vs AVQ distance which determines the scenario of the match, always discarding players of both teams, and this has been visually proved in these teams that have for example 5 1*'s and 6 players 7*.... a team like this playing with a full 7* can draw if the game choses the good players but same time if the game chose as protagonists and determinant players the 1*'s to face the 7*s of the other team, you can lose 6-0 perfectly due this "technicallism" of the simulator used to create different scenarios with different players interferring in every match.
Internal programming, dear, internal programming.
