.1
Players can be internally more proggrammed o attack, been defenders, or defend, been a ST playing as AMC for example.

.2 every match have scenarios with %'s of aggressiveness increased in players, to make us manage, in same sense, we do not see all the names of teh 11 players with the intention to make us manage and do sub's for players that can contribute better, and too, with the selected players every match have system to make them contribute more attacking or defensive. Probably this last factor depends of the player tendance proggrammed by default. So is a ST with more defensive tendance is selected to appear more this match, the contribution will be based in the proggramming by default. Ive seen many MC's during ma 38 seasons that really participe continously in defense work and really are key there many times, despite they do not contribute a lot maybe in attack by my viewpoint these have a special consideration.

.3 Evey option in the game, affect just a little %. Ive said that in ma Guide in Spanish (there's teh condition, morale, orders, bonus victory, possesion attending, susbtitutions, quality...) so, the arrows are the same, touch in some % the tendance to attack/ defend of players.
despite red arrows in ST's, they can appear in defense, if, are the men selected to participe more in the match + men to appear to save in defense.

All is a bit strange, but have of T11 what it is. All, affect a little %. Except the things that affect in a more deterninant way.

PS: I play with 10 arrows. lol
