None of the variables in the above portion of your post are even moderately correlated with the percentage of sacks taken on pressured dropbacks by quarterbacks league-wide. In other words, it's implied that they're related to (or cause) sacks in the article, but they are not (and do not).Other than being benched?
How about this:
There are certainly times where Tannehill could get rid of the ball more quickly, but a video breakdown of his pressures and sacks from Weeks 1 through 4 of the 2013 season paints a grim picture for the offensive line.
Tannehill has regularly had far less time in the pocket than he needs to reasonably go through his progressions.
The defenders are often found to be closing in on Tannehill within 2.5 seconds of the snap. That is not nearly enough time to go through progressions.
According to ProFootballFocus.com (subscription required), Tannehill has often been under pressure very quickly after the snap. He's spent 2.5 seconds or less in the pocket on 64.9 percent of his dropbacks, which is the second-highest percentage of such passes in the league.
His 4.3 seconds to scramble on average and 3.6 seconds to be sacked on average are both the sixth fastest in the league in those categories.
As mentioned above, though, it's not about his inability to get the ball out quickly. His 2.28 seconds to attempt a pass on average is the second fastest.
Why do you suppose that view is in disagreement with that of a would-be Hall of Fame wide receiver who played in the same offense, here?How about this article?

"Tannehill was officially sacked just twice, but his ability was the primary reason why the sack number was so low and why the offense was able to put points on the board. Tannehill, a former wide receiver in college, is quietly a very athletic player who can escape pressure with his feet or throw strikes deep down the field even when throwing from tough body contortions."
"The Dolphins' biggest play of the day showed off Tannehill at his very best. The Bills defense shows a single-high safety look before the snap, but that safety is shaded to one side of the field. This leaves Wallace at the bottom of the screen in single coverage against Stephon Gilmore. Although Gilmore is an excellent man cover cornerback, he is still rusty after missing much of the season recovering from injury.
Even though he has a receiver to that side of the field, Tannehill doesn't look directly at his receiver or at the deep safety. Instead he looks towards the sideline on the opposite side which draws the safety slightly over the hash mark. He looks at the safety and back to the sideline twice before looking back to the other direction for Wallace. Meanwhile, Wallace is struggling to get into his route.
Gilmore initially has excellent coverage by jamming Wallace at the line and then turning so that he is in perfect position to run with him down the field. However, at that point Gilmore’s concentration inexplicably seems to go as he drifts infield while eyeing the quarterback too long. That failure by Gilmore combined with Tannehill's manipulation of the deep safety creates a huge window for Wallace to run into.
While Wallace is getting open, Tannehill is unable to step into the throw because of a defender pushing his blocker into the backfield, and then putting his hand in Tannehill's face as he releases the ball, while his blocker knocks into Tannehill’s feet during his throwing motion. Regardless, Wallace is still given a near-perfect pass to run under as he sprints down the sideline. Plays such as this showed off his poise, but also his athleticism, anticipation, velocity and ball placement."
