May data comes from the snap of the ball (running timer) to contact, not the whistle, who gives a **** how long it takes between the whistle blowing and the snap of the ball.
PFF dropped the ball on this one, just like Cold Hard Football Facts did when I pointed out the obvious flaw in their newly minted running back rating system. They counted fumbles as a negative value toward the running back and not fumbles lost, in the QB rating formula you count interceptions, not nearly interception. It skewed the data and the same thing is happening here with PFF in this case,
if QB A takes x amount of time to survey the line of scrimmage after the whistle is blown and QB B takes y amount of time, x is not equal to y thus influencing time to sack when measured this way. The average time you want for your QB to throw is 3 seconds, from the dawn of the new passing era that is the time you want and the bench mark, not 2.5 or 3.5 but 3.
Notice on your beloved site where 2.48 ranks Ryan Tannehill in terms of the "whole" NFL in 2012.

Yup that's right 31th. Notice on page 2 of the same write-up that PFF prints in black and white that Ryan Tannehill on 60% of his snaps in 2012 had less than 2.5s to throw, good for 3rd worst in the NFL.
And if you care to look at page 3 of this write up from PFF it clearly states the following:
This offensive line is not better than last year, it isn't. Tannehill doesn't have the time to throw that he needs, he is constantly under pressure. With that said I put the loss on Sunday squarely on Ryan Tannehill, you still have to hold on to the ball and he is fumbling at an alarming rate. You have to know a bull rush is coming and your line sucks ass, you take a quick read, if it isn't there take the sack, punt and put the game on your defense.
The time to throw is horrible for Ryan Tannehill, just ridiculously horrible but he can still do some things to improve the results.
