With Tannehill it was 6 years before we gave up. But if a QB like Watson had been available, we would've pulled the trigger. Tannehill is succeeding because of elite talent around him in Henry and Brown. He also has a stronger arm and better mobility than Tua.The problem isn't Tua. Giving up on him after 13 games is kind of telling to where we are today.
MIA can win with Tua, but his upside is a midrange QB like Bridgewater based on what I've seen thus far. I'm not sure why Watson wants to come to MIA given that the team has less talent on offense than PHI or CAR.
