It's Tua Time in Miami, and the immediate question is why now? It was well known that 2020 first-round pick Tua Tagovailoa would eventually become the Miami Dolphins' starting quarterback, but coming off back-to-back blowout wins does not seem like an ideal time to switch things up.
Most would have been fine with Tagovailoa sitting for longer, or even all of the NFL season, and learning behind veteran quarterback Ryan Fitzpatrick, who had been playing very good football through six weeks. But after taking a step back, this move makes a lot more sense.
