Interesting, Is Justin Herbert the guy that can put a team on his shoulder and win? If so, What happened this season? I mean he had more attempts and a billion yards..Yet?
What happens if he played in Miami under the exact same circumstances?
Well considering what the questions were for Herbert coming into this season, it's very easy to say that the doubting scouts were wrong. Everyone knew he had the tremendous physical attributes, but they all questioned his skill. Everyone except maybe Chris Simms and Paul Bermeister seemed to discount the crappy Oregon offense. So when Herbert dropped into the NFL and had great success, most of those analysts who predicted he would be a project at best were proven wrong. Yes, like most rookies, he had some bumps in the road, like when the Dolphins played to tendencies and trapped him into throwing at Xavien Howard, who outmuscled the WR and stole an INT. Bad decision from the rookie to make that throw ... but he didn't have nearly as many bad decisions as people expected.
To your question about putting a team on his shoulder, yes, Justin Herbert single-handedly put the team on his shoulder multiple times as a rookie, producing lots of points. With that defense having a healthy Joey Bosa, Melvin Ingram, and Derwin James, I suspect Herbert wins more of those games. Moving forward, it sure looks like Herbert can carry a team and lead his offense to scoring points. The defense ... that's out of his control. Maybe with a new coaching staff they can fix that. If not, having better luck with health should definitely help.
Is Tua responsible for our wins ? In part, yes. But we started our win streak under Fitz, and he was part of our success too. But the largest part of our win streak was the emergence of our defense as dominant, and Tua's good decision making and avoiding of INT's helped us win those games. For a defensively dominant team--which is exactly what we were when we won--having a QB who doesn't throw INT's is huge. Fitz was the better QB, but Tua was the safer QB, and that is incredibly rare in a rookie.
Herbert didn't have the luxury of a dominant defense constantly taking the ball away and giving him possession while ahead in the game. The Dolphins defense not only stopped the opposition and created takeaways, in the first two games Tua played they also actually scored. That is rare. In Tua's first start, the special teams scored as well. Both the special teams score and the defensive score were 80+ yard plays and huge momentum swingers. Herbert simply didn't have that kind of a defense.
IMHO, if Herbert played in Miami we would have won at least as many games, and definitely scored more points against the Bills. But, Herbert would have thrown more INT's as well, so the final record may have been the same or possibly more or less wins. Tough to say. But, we would have scored more points against Buffalo, I'm confident of that.
Can we be confident that Herbert can put the team on his shoulders? IMHO, yes, because he has already shown he can put up points against lots of NFL defenses. Can we be confident that Tua can put the team on his shoulders? IMHO, no, because while he had encouraging games against Kansas City and Arizona, he hasn't really shown he can score a lot of points, nor has he shown he can score on any defense. What he has shown is that when our defense is dominant, he can manage the game very well and protect the ball.
Next year Tua's hip should be fully healed. That will allow him to torque his hips and carry throwing power from his base through his hips and arms and result in better velocity on the ball. He should also have more confidence in his body, because the psychological aspect of this kind of injury often lingers past the physical ailment. Having had reconstructive knee surgery myself, I have sympathy for Tua enduring that hip injury.
