I’ve already posted earlier in this thread or another one but league passer rating average is around 91.
In the last 2 seasons Tua has had 9 games were his passer rating is 92 or below. The Dolphins are 1-8 in those games.
The Bills have 15 games in the last 2 seasons were Allen has a 92 rating or lower. They are 9-6 in those games.
This Miami team doesn’t win unless Tua plays better than average. That’s a lot of pressure to put on your QB every time he steps on the field. They have to find a way to win games when Tua is average or poor, other teams find ways to win games in those situations.
This argument has become somewhat common in the last few weeks as it makes its way around the internet but I don't think it's convincing anyone, IMHO.
What people are complaining about is something we all see. When the Tua offense doesn't work, the Dolphins offense as a whole looks mediocre and sometimes downright stagnant.
The Tua offense is highly scripted and based mostly around quick throws to the short-to-intermediate areas up and between the numbers. When that element of the passing offense is taken away by a good defense, Miami's Tua-centric offense doesn't have the traditional drop-back content or the new-school scrambling element other offenses turn to--and McDaniel doesn't feature the run enough. So blame him, too.
There's a reason that when Tua's stats aren't good the Dolphins lose...it's become they don't do the other stuff that's required to counter.
So the poor record(s) you're pointing to...are they a defense of Tua as a QB or are they a critique of the limitations we should expect from an offense built around Tua? Granted, if Miami had better pass protection, I'd feel better about Tua being able to step into more throws outside the numbers. That can't be understated.
To me, it goes both ways. As a professional NFL QB, Tua has to attack outside the numbers with conventional drop-back passing and scramble more consistently at least to the extent that Dak does (~200-yds per year). He's probably never going to do either consistently so a good defense can defeat him. It's not impossible though. Tua was on pace for almost 180-yds during his 2nd season under Flores. He needs that element in his game.
Truth is, Tua made a lot of plays with his legs in college, a lot of plays that were reminiscent of Russell Wilson. I think that's what we all thought we were getting. The last 2 years, Tua hasn't done much running at all and it's limited the offense. While he's remained healthy this year, the offense lacks a counter when the middle of the field and the seams are covered. It's not a perfect offense.
If Tua runs more, there's a chance of injury. If he throws outside the numbers the INTs will likely go up. It makes sense that taking on more risk may be a bad thing but that's precisely why the Dolphins often have bad games and flat out lose. When it works, it works. When it doesn't, there's no counter.
