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

what you DON'T analyze/point out is the comparison of the % of sacks allowed by line vs. % by QB. If these numbers are accurate, RT ranks #6 (with Brady ranked #1) in the % of sacks allowed compared to his line's .

In other words, there are only 5 QBs ahead of him when ranking the QBs on "least to blame" for their sacks. Our OL sucks.

The aspect that jumped out to me was the athletic quarterbacks are responsible for a higher percentage than typical of sacks attributed to the quarterback, while the classic pocket types have very low number of sacks attributed to them. In that regard I don't see how this is good news for Tannehill, if we consider him a pocket type. Virtually all the classic drop back peers are below 2% including young players like Luck and Dalton. Only Flacco among the pocket types had a lousy number at nearly 4%. The elite guys like Brady and Peyton are below 1%.

With poor numbers for all the athletic guys like Newton, Kaepernick, Wilson and Griffin, plus the Buffalo quarterbacks, I would be interested to sit in the office when this type of stat is evaluated. Seems likely that it is skewed against that type of quarterback, even if unintentionally. For example, if an athletic guy makes a quick decision to bolt the pocket and is sacked, they tend to blame him, while with a classic quarterback who hangs in there and doesn't move the sack is credited to the offensive line.

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've been saying this before the season started but I think the skill level of the players responsible for pass protecting is overrated. There are 3 key areas that account for good pass protection and they are all equally important to mitigating sacks imo:
1. Coaching. Play calling, protection schemes etc.
2. QB. Making adjustments, reading defenses, pocket presence, etc
3. Skill level of the actual pass protectors including the RBs

I think we're below average in all 3 areas which is why we're seeing historic type sack numbers but the skill level of the pass protectors has been absolutely woeful.

Pro Football Focus keeps a stat called "pass blocking efficiency," which it says "measures pressure allowed on a per-snap basis, with weighting toward sacks allowed."

Now I don't know what that means, but I decided to take a look at the proportion of the Dolphins' sacks PFF attributed to blocking, versus the proportion attributed to Ryan Tannehill.

The Dolphins have had 58 sacks on the season. PFF attributes 41 of those to the Dolphins' blocking, and (apparently) the remaining 17 to Tannehill.

The table below shows each NFL team's number of pass plays, its total number of sacks, the percentage of its pass plays in which a sack occurred, its sacks attributed by PFF to the team's blocking, the percentage of its pass plays in which it had sacks attributed to blocking, its sacks attributed by PFF to the team's QB, and the percentage of its pass plays in which the team had sacks attributed to the QB:

So we can see here that the Dolphins are well above the league norm in total sacks, well above the league norm in its percentage of pass plays in which a sack occurred, well above the league norm in sacks attributed to blocking, and well above the league norm in the percentage of pass plays in which they had sacks attributed to blocking, but not significantly different from the league norm in either the number of sacks attributed to the QB, nor the percentage of pass plays in which they had sacks attributed to the QB.

This lends support to people's perceptions that the offensive line has been far more at fault than Ryan Tannehill for the Dolphins' inordinate number of sacks this year.

None of these sacks were Tannehills fault you hater. Get a grip. He can't block for himself and throw with pinpoint accuracy all over the field.
 
All that stat shows is that the notion that "Tannehill holds onto the ball to long" is total BS!!!!
 
Sometimes Tanny has 2 seconds or less. The oline sucks and the RB's and TE's can't block either. Anyone who's not blind can see that. But hey, lets give Ireland 4 more years and he'll fix the oline. You can't expect him to fix the problem in only 7 years.

Ozzy rules!!
 
this is the problem.

Sherman and his use of the TE's to block and decieve a defense.

When we use our TE's to block (as opposed to having Clay back there to block, hence taking him out of passing game), we play much better. We had our other TE's for 14 snaps.

How long would it be for any of you to get this friggin clue????? I am no expert, but you have to have a keen eye on whats not in vs. whats in when things work and dont work.

Sherman didnt use his TE's. He didnt use them when we started losing. He started using when we were winning. I cant be any more direct than this.

To be fair, Sherman was probably giddy thinking about what he was going to be able to do with Keller and Eifert as his TEs. Instead he got Egnew and Sims.

To be fair, if he had pounded the table for Eifert, Ireland probably wouldnt have gone up for Jordan. I watched Hard Knocks. The coaches were set out to find a TE and not mess this one up and they went to Sims. Which is a good pick IMO.

They just will not put any trust in the rookie to do anything this year. I would think they will take the offseason to make him a much bigger part of this offense next year. For now, wax on wax off.

and Keller was a killer deal for Sherm. That just totally sucks for all involved. And that is being fair. Ireland helped get him in here for one year. But none of that matters now. to be fair.

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.

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.
