Bear in mind that perfect QB has to play behind Miami's line. Maybe I'm not that critical of whether Fitz was pinpoint accurate when nearly any QB in the league wouldn't have been able to get the ball off at all regularly with our train wreck of a line, much less make big plays consistently.
Tannehill has shown he can be pinpoint accurate downfield. That's what he did with the Titans last year, and he showed that under Gase as well. With below average lines, how often did that matter? He rarely found a way to get the ball out with the way our team played - and I'm not disparaging him because of that as much as I'm trying to promote what Fitz did.
