PFF: Tannehill's Sacks vs. Dolphins' Blocking Sacks

All I can say is thank you for posting this.
You're welcome. I know we've gone 'round and 'round here at times, but like I've said, I do these analyses with an open mind, and whatever comes up, comes up, and I'll post it either way, regardless of how it fits with what people believe, myself included. :up:
 
One thing to add to this thread. The play of the OL (when it is this bad) HAS to impact the passing game on the all the passing plays. You have to game plan around it. It has to affect your QB (although Tannehill has seemingly held up well). The sacks put you in poor down and distance situations, which leads to other bad plays. Add in the pathetic run blocking which leads to bad down and distance and killed drives, and the situation looks even worse.

Tannehill has to feel like he is playing by himself sometimes and has to hit every single throw. That kind of pressure cannot be good.
 
All of his previous posts on the topic put the blame on Tannehill because he didn't have the stats that "he required" to put the blame on the OL. Well, I tried to tell him that he didn't have the stats to put the blame on Tannehill either and the film showed the problem was with the OL. He flatly refused to listen.

I gave him credit for posting this. It does show guts to post it here.
I'm not sure I flatly refused to listen. What I said was that the film didn't give us the proper information to decide either way.

I view this very much like instant replay for referees in the NFL. They believe they saw something on the field, and they go to the instant replay booth to confirm or disconfirm it. Sometimes they can say nothing either way because there is no camera angle available to provide the definitive evidence. That's how I viewed the film with regard to the relative responsibility for sacks between the offensive line and Tannehill. I just don't think the normal angles we see on TV provide the necessary information either way, at least in a number of cases large enough to make the crux of the matter inconclusive via those means.

If I could offer a friendly piece of advice (before we are at odds again), IMO, on this topic, you took the absence of data blaming the OL (or tangential data favoring the OL) as evidence that Tannehill was at fault. Primarily I am thinking that the % of plays where the QB was pressured wasn't above normal, you took to mean that the % plays that the QB was sacked where the OL was at fault would also be normal. I never believed that.

Also the PFF OL grade was middle of the pack. I think the way they aggregate the numbers obscures the OL play. As a said, if 4 out of 5 kill there opponent, and the 5th gets burned for a sack, the overall grade for that play is good. We say a lot of individual failures on the OL this year.

Again, I'm trying to sort out my own confusion regarding the objective measures of blocking, and how they're all at average levels for the Dolphins.

With regard to what I bolded above, we have a problem in that regard, because PFF's pass blocking efficiency stat is correlated with sacks attributed to blocking at -0.64, and its pass blocking grades are correlated with sacks attributed to blocking at -0.60. Percentage of passing dropbacks in which there is pressure is correlated with total sack percentage at 0.65, and with sacks attributed to blocking at 0.53.

Given what I said earlier in the thread here:

This is precisely what's happening. The correlation between QB sack percentage and QB yards per carry on rushes (a hypothetical measure of QB athleticism) is 0.66.

When the variance associated with PFF's pass blocking efficiency stat (which by the way correlates with its pass blocking grades at 0.96) is controlled for (i.e., in a partial correlation), the correlation between QB sack percentage and QB yards per carry on rushes is maintained, at 0.67. When the variance associated with the percentage of dropbacks in which there is QB pressure is controlled for, the correlation is 0.58.

In other words, more athletic QBs are having a greater percentage of sacks attributed to them, regardless of the quality of their pass blocking, and regardless of the frequency of the pressure they experience when dropping back to pass.
...I'm still stuck as to how to explain how the Dolphins are rated as average among these pass blocking statistics, given their horrendous number of sacks on the year.

I don't think a "thanks/no thanks" button is going to change the way I do business, pal. Thank this.

Dunno about that seeing as it was removed as punishment for some.

Its not about you, its about everyone else. And I'm pretty you you have said at least 2 times that you blocked me. I knew you couldn't stay away for my wonderfully insightful posts.

We're here to talk about the Miami Dolphins, not meaningless individuals who call themselves "Zounds" or "shouright" on a message board.

The only one talking about you is you. Get over yourself. Giving a "thank/no thanks" is a way to communicate agreement or disagreement, and we are here to communicate.
 
Merry Christmas buddy. Hope you get a new choo-choo train from Santa. BYe.
 
I'm still a bit confused, however, as to why every objective measure I'm aware of, including:

1) PFF's pass blocking efficiency stat;
2) PFF's pass blocking grades; and,
3) the frequency of pressure experienced by the quarterback when dropping back to pass,

...show the Dolphins as performing no worse than the league average.

How do you get that? According to the OP our o-line was responsible for 41 of our sacks, the league average attributed to the o-line is 22 and the next worse o-line was the Patriots with 33.

Not only are we not worse than average, according to those numbers we are the worst. What am I missing?

...hence the confusion.
