Both the team players and coach all have to be be identified as unique contributors that determines what the team achievement is, we also have to go furthermore looking into the internal conditions with some of these teams and see how things are going on beyond all we only see online through their performance during their matches, a lot are going under from the decision making process and this also have something to do with how the team players or coach performs.
I think that everyone is responsible because the team is a single entity. However, I am a fan of team sports and even often bet on them. I never feel negative emotions even if they lose because I understand that there are many factors that are simply impossible to determine for a victory. Even if we take them all into account, the wind blows in the wrong direction or the main player gets an old injury and the game goes in a completely different direction. Personally, I am never going to blame for this, even if I lose money on bets.
