This is not meant to be offensive to anyone but I think this might be an issue of low standards.
24 of 27 pass plays is 89%. 15 of 19 run plays is 79%. Altogether that's 85%. That's not really that great, especially not against Sione Fua the rookie 3rd rounder.
The most concerning things were:
A) The consistency of his failures in certain situations (e.g. goal line), and
B) The consistency with which his best plays and best attributes (getting out into space) went unseen and/or unrewarded due to the insufficient blocking around him.
We're not just grading on the basis of "for a rookie" here. He's a starter. He's the 1st round pick. He's the guy that the Dolphins took at #15 overall when they could have taken any number of other guys, such as Mark Ingram. That forces you to assess his impact on the team relative to others. I raised the question when he was drafted...how often is he going to be show great things that Joe Berger did not or could not show, that ALSO impact the success of a play? In other words, how much impact is he going to have above a Joe Berger? Everyone just naturally assumes the guy is going to be better than Berger, be more impactful. But that's not what I saw the other night. I saw a guy who is better than Berger in space and out in the second level, but whose talents in that area were wasted by bad blocking from his fellow lineman, and I saw a guy who didn't have near the strength at the point of attack that Berger had, especially in those short yardage and red zone plays. So his weaknesses relative to Berger got exposed, while his strengths relative to Berger got drowned.
And that is a concern.
