Now I will make you all discuss
Not agree. Really looking the teams and knowing the game I don't see the troll, I repeat, "knowing the game".

Yea, when that happens people look that are 4-5-6 players under the field, lots are out of position sometimes too, due expired contcats this situation happens to abandoned teams and so.

Illegal position mean nothing many times, the game will do the simulation taking into account 1st the Quality, 1st of all.
Then... game do the simulation, simulation are chances. Chances are to fail or to score.
I always, always defend the idea that 1 player can win the 80% of a league title, so I will contradict myself if I come here and say that 3-4-5 players OP and a team with 20% possession winning or drawing are like to do a football a crime.
