This means that if the St. Louis Cardinals were to move him, it would have to be a team of his choosing. This would limit the pool of teams St. Louis can work with. On top of the no-trade clause, Arenado has expressed that he would like to stay in St. Louis.After the season was over last year, Arenado declined to opt out of his contract and become a free agent. He loves playing for the Cardinals and does not want to leave despite the team's poor first half.The same could be said for Paul Goldschmidt, where rumors about the team trading him are circulating. Neither player wants to leave the team and likes how the Cardinals' organization carries itself.
