Wasn't Belichick always super harsh on Tom Brady? Different players react to different coaching styles and all that but this sounded like it was personal. Like Flores didn't want Tua so he was just dogging him out nonstop. Not a great look.
Some coaches aren't doing it for motivation. Some coaches are just jerks who get off on humiliating certain players. I don't know if that was the case here but anyone who had to play for a jerk like that knows exactly what I'm talking about.
