Visualizing The Hennechart

I like the new Hennechart and thanks for including a legend.

I know it would be hard to read for small samples, but attempts should not be normalized (or better we should see both.) A 5 attempt Wisc game comparison to the 32 attempt OSU game for Henne '07 says there is more to that story than the Hennechart.

You really see the Iowa drop off for Tate. PSU is going to be much better IMO.

Not sure if this was brought up in the original diary, but this graph could be improved with a 90 degree rotation. That would put it more like a standard bar graph. It's easier for peoples eyes to decipher relative heights as opposed to deviations from center.

other than that, great work. graphs really help to send a message home more clearly, and i think you've done that

I'd suggest moving Throw Aways to the far left of the bad category (as the color coding implies). If this is a QB metric, a throw away is often a good decision based on lock-down coverage - a sign of maturity and solid decision making. If its a Passing Offense metric, well then, its a bad thing obviously.

For a QB evaluation it should be treated somewhat like Marginal - neither good nor bad. Maybe even center it at 0.

You could make a similar argument for moving Pressure or even Batted, but theres nothing good there from the QB's perspective, whereas TAs might be/probably are a good thing.

Also, a request for an aggregated chart for each of the last few seasons. This would be cool as well.

Could we also re-render the '06 Henne chart so it's of the same scale as the rest of the charts? Although the bars are proportionally correct, the smaller sized bars make it easier to misinterpret the chart.

I was reading a piece from the Ann Arbor News recently and I was struck by the thought, "Wow, this author is an idiot." And then I thought about all of the awesome and in-depth coverage by blogs like MGoBlog. This site just has to be advancing the general state of sports journalism and probably journalism in general.

On the above chart, wow. Brian's original Hennechart was a remarkable advancement, but this further chartified incarnation is amazing. I don't know where this skill set comes from, but it is flabbergastingly impressive.

You guys rock. I can't wait until you are the mainstream and we can go to a site like the Ann Arbor News and get real news and analysis.

Interesting charts, however, it's a bit hard to distinguish the blues from each other. Changing one of those colors a bit would make the charts easier to read.

Look at the dropoff for Tate against Iowa! He really was having a terrible game and his removal looks justified.

This is fantastic. I know Brian is fond of charts, but it really is amazing how much easier it is to digest data when it is visualized in a graph. I particularly like having each game stacked on top of the previous so that differences are more readily appreciated.

You're welcome for all the thanx!

I still wish we could change the "TA" stat to "RA" , "RA+" , and "TA" to account for scrambles that get good yardage.

It seems unfair that Tate's big chunk of yellow counts against him, when a "TA" from him gets the same exact result as a 7-yard CA from Henne.

This is excellent. Do college coaches use a metric like this each week to grade out their QBs? Also, does anyone have an idea how Terrelle Pryor would grade out on this system? I was in Cleveland this past weekend attending a relative's birthday, and man, is that dude in hot water. The whole state is blaming him for tOSU's troubles. Glad we got Tate.

Very good job here. Kudos for the hard work.

I enjoyed the visualizations of the chart. Nice job

on trying to analyze QB's throws in each game. Completion percentage is not a good judgment of how accurate a QB is unless you're Jamarcus Russell(Zing!).

First, here's a pie chart of my favorite bars.

Now, here's a bar graph of my favorite pies!

Save images as PNG instead of JPEG. You'll keep a small file size with much better image quality/clarity.

I think collapsing each chart into one cumulative chart would allow you to place Henne, Threet and Forcier right next to each other and make it much easier to see the differences between the QB's.

It will allow us to compare the first 6 games of each QB on 1 chart with a consistent line of sight (vs. having to lower and raise our eyes to compare game performances).

Also, agree that throw away should be close to 0, or maybe even removed, as it is generally a smart move on the QB's part.

I am looking at, but it looks like it involved quite a bit of research. so good job. I can't wait until a few weeks from now when I have my Hennechart epiphany and it all makes sense.

I smell nerd.

Not like that's a bad thing.

T. Waymen, you are a Venn Diagram genius.

He who smells nerd, well, correct.

Your charts are a fantastic compillation of information, legible at even a glance. Very well done sir.
