Carr did get angry at Olave during a game.
Please point out any press conference in which Carr openly blamed a player for something, any player not just Olave.
Getting angry with a player during a game is not the same thing as blaming a player for something during a press conference.
For instance, McCoy got really mad at Carr during a game. Remember what McCoy said when asked about it in an interview after the game?
So again, point to any instance of Carr blaming a player for something during a press conference or interview, since has been a Saint.
