Tua Tagovailoa is doing one thing with any degree of consistency; he is proving Miami Dolphins fans are right about his status as a franchise quarterback, but this loss wasn't on him.
On Sunday, the Dolphins didn't lose because Tagovailoa was the quarterback, but they didn't get much help from him either. Whether it was ill-advised throws, interceptions, or poor judgments, Tagovailoa struggled throughout the game and even led what should have been a game-winning drive. It was still just too much.
Miami led in the first half, but as the defense collapsed in the second, Tagovailoa and the offense couldn't overcome his inconsistent play, and the defense couldn't stop the Chargers when he finally did it right.
