During a pre-game preview, ESPN analyst Richard Jefferson made the mistake of mentioning Isaiah Hartenstein as a player to watch for in the matchup between the New York Knicks and the Dallas Mavericks. However, Knicks fans were quick to point out that Hartenstein was no longer a member of the team, as he had been traded to the OKC Thunder this summer. Despite trying to correct himself, Jefferson faced criticism and backlash from social media users for not being well-prepared for the game he was calling.
