Quote:I like the first one alot, second is harder to read, but it clearly shows that Bortles hasnt had any 'really good' games this season. Neither has Oswieler tho either.

 
The weekly graph can be deceiving. For instance the difference between Mariota and Luck looks to be about the same as the difference between Bortles and Osweiler. But there is only 1 QB (Keenum) between Bortles and Osweiler and 5 between Mariota and Luck.
 
Only Fitzpatrick currently has a lower rating than Osweiler.
 
Half the league separates Luck from Bortles.
 
There are only 4 QBs above Mariota: Brady, Ryan, Prescott and Brees.
 
On the Opponent graph each column should be viewed as its own separate graph. Don’t try imagining trend lines across the columns. The purpose of the graph is to directly compare how each passer performed against the same defense.
 
Just going by the Defense Rate markers you can see that the average team defense passer rating this season is around 90. Through Week 13 the actual average defense rate is 90.7 across all NFL teams. 
 
The left side of the graph shows the 1v1, 2v2, 3v3, 4v4 matchups against the AFC North and East teams. 
 
Here you can see Mariota feasted on the Browns who have the worst passing defense in the NFL. 
 
Mariota also played very well against the Dolphins who have a slightly above average rating.
 
Bortles will have faced the toughest AFC North or East passing defense in the Ravens. And of course, Bortles had a poor passing game against those Ravens.
 
Luck has the best rating which came last week against the Jets.
 
The Steelers are not included since Luck sat out that game.
 
The middle portion of the graph is the most useful for comparing the QBs. Here we have the NFC North and AFC West matchups.
 
Mariota really feasts on weaker Ds in the North.
 
Bortles and Osweiler are having terrible horrible no good very bad seasons.
 
Osweiler’s best performance was against the Packers last week so it might look like he’s turned a corner but the Packers have the second worst passing D in the NFL.
 
Luck’s supposed to be a HoF QB? Luck looks like Just Another Guy as his numbers in this portion of the graph seem to average out to just average. Meh.
 
The right side shows the home and away games in the division. I didn’t separate out the home/away defensive rates. The rate shown is over the entire season.
 
The Colts have the worst passing D in the division and its not really close. So maybe Luck is a HoF quality QB?
 
If you only looked at the weekly ratings you might think that Luck is ascending and Bortles went off a cliff last week but really they just happened to play a weak team in the case of Luck and the best defensive passing team in the case of Bortles.
 
The weekly graph shows that Bortles and Osweiler are consistent. The lone outliers are Week 13 for Bortles and Week 12 for Osweiler.
 
Bortles had only two average to above average games one of which was the Titans, a blowout game where Bortles picked up some garbage time points. The Jaguars were actually only blown out in two games, Chargers and Titans.
 
Mariota has had up and down weeks but his down weeks were still average or above since his poor Week 3 and 4 performances.
 
Considering the other 3 QBs did poorly against the Broncos, this week should be a good indicator if Mariota’s passing game is “there”.
 
Mariota is the MVP of the Titans. When he has elite passer ratings the Titans win. Average to below average passing game = loss. This might seem obvious but it doesn’t hold true for Luck.
The Titan’s exotic smashmouth running game may be helping Mariota’s passing numbers but it doesn’t appear to be winning games without Mariota being an efficient passer.
