The Jets (0-6) became the NFL's only winless team and continued their worst start since 1996, increasing the heat on embattled second-year coach Adam Gase.
The Dolphins blanked the Jets for the first time since the January 1983 AFC championship game, which they won 14-0.
The Dolphins' only third-down conversion came on a completion by Tagovailoa, who went 2 for 2 for 9 yards.
After the game, Tagovailoa spent about several minutes sitting alone on the field and on his phone with his parents.
