Tua Tagovailoa returned and with him came a slew of bad habits from this team's early start to the season (and years past). The Dolphins moved the ball at will at times but suffered from self-inflicted errors that ultimately snowballed and came to a head amid an awful second-half performance from the defense. Miami falls to 2-5 on the season thanks to a walk-off field goal by Arizona, leaving this season dead in the water. Where do things go from here, besides down?
