Yet another Henne post. (With some Hartline)


I was looking at the game logs for Henne and saw that there was something that caught my eye. It was the difference in performance before and after three injuries. The injury to Henne that should have sidelined him for the rest of the season, the injuries to the OL and the injury to Hartline. 

 

Before Henne's injury

 

Completions     195

Attempts           305

Completion %    63.9

Attempts / Game   34

Yards                2140

Yards / Game     238

YPA                   7.01

Touchdowns      9

TD / Attempt      2.95%

Interceptions      11

INT / Attempt       3.6%

TDs / INT             .81

Average of QB ratings  80.9

S.D.   15.4

Median  of QB ratings   82.3

IQR                            18.8

Since the Average is less than the Median, it seems like the data is skewed to the left.

I made a histogram of the data and it seems like the QB rating from the BAL game is separate from the rest of the data. But is only just over 2 S.D.s from the mean, so it is only unusual. 

(Those last four aren't usual stats, but I thought it would be interesting to see them.)

QB Rating               79.3

1.695 + 1.00 + .590 + 1.473 = 4.758

After the Injury

 

Completions       106

Attempts             185

Completion%       57.3

Attempts / Game   31

Yards                 1181

Yards / Game      197

Yards / Att           6.4

Touchdowns        6

TD/ Att                3.24%

INTs                    8

INTs / ATT          4.10%

Tds / INT            .75

Avg of QB ratings  63.5

S.D.                     28.6

Median of QB ratings       65.1 

IQR of QB ratings            49.1

 

 

Since the Average is less than the Median, it seems like the data is skewed to the left.

1.365 +  .846 + .649 + 1.294 

 

QB Rating                    69.2

 

As you can tell, Henne's production dropped significantly after his injury. Also, it should be noted that this injury was very serious and he probably should have been IR'd If he was able to keep up the same production before his injury throughout the season (which wouldn't be unrealistic given that the hardest part of the schedule was the first half). He would have done:

Completion % = 8th best

YPA = 16th (Tied with Brees and Farve)

Yard/ game = 14th

QB Rating = 24th

Yards = 3808 (extrapolated over a 16 game season) = 9th

 

Before Hartline's injury

The only difference in this over what is above is the OAK game.

 

Completions                   212

Attempts                         335

Completion %                 63.3

YPA                                7.3

Yards per Game            245

Touchdowns                   11

TD / ATT                       3.28%

INTs                                 12

INT / ATT                       3.58%

TD / INT                           .92

Average of QB Ratings    82.9

S.D.                                  16.6

Median of QB ratings       82.6

 

1.664 + 1.076 + .657 + 1.479 = 4.876

QB Rating = 81.3

.905 + .625 + .516 + 1.246 = 3.292
QB Rating = 54.9

I think the biggest impact Hartline had was Henne's YPA. I think this is just more evidence that Hartline is a big play WR that can stretch the field.
