I don’t think there’s a definitive list, but these are the 8 in-game flopping techs I know of:

• Brunson - offensive
• Thanasis - defensive (off ball)
• Oubre - offensive
• LeBron - defensive
• Porzingis - loose ball (offensive rebound)
• Ziaire - defensive (can’t find video, but from twitter comments)
• Dort - defensive (off ball)
• Garland - defensive (off ball)
