Basketball reference here, Tracy Mcgrady was the best scorer in the NBA, great player but he never made it out of the first round of the playoffs, oltough he was great player and troughtout his carrer he played in mostly bad teams, he's labelled as a choker because he couldn't make in the biggest stages ( playoffs ), same for Zingaro, he never made it in the biggest stages, he always goes missing in big games and wait for his teammates to save him. That's a choker for you.
