## Checkdowns: College Football QB ANY/A, 2014

Adjusted Net Yards per Attempt is the basic measure I use to measure quarterback performance. ANY/A, of course, is calculated as follows:

(Passing Yards + 20*PassingTDs – 45*INTs – SackYardsLost) / (Sacks + Attempts)

Finding college football sack data is notoriously challenging, but ESPN does at least list sack numbers (but not sack yardage lost) for quarterback. But if we assume each quarterback loses 6.7 yards per sack1, then we can calculated estimated ANY/A. And we can also calculate estimated value.

This year in college football, the average ANY/A is 6.13. Let’s use Oregon’s Marcus Mariota as an example. The Heisman frontrunner has thrown for 2,780 yards and 29 touchdowns on 277 attempts, while being sacked 23 times and throwing just two interceptions. As a result, Mariota has an ANY/A of 10.39. That’s 4.26 ANY/A above average, and over the course of Mariota’s 300 dropbacks, that means he’s provided 1,278 of Adjusted Net Yards of value over average. As it turns out, that’s the most in college football. The table below is fully sortable and searchable, and it lists the 172 quarterbacks this season with at least 50 pass attempts:

• It’s important to remember that much more so than in the NFL, strength of schedule is a significant variable in all college football analysis. That is completely ignored here. In addition, coaching and scheme matter more, too, and that is not considered in this analysis. This is simply a quick and dirty look at the numbers.
• Jameis Winston checks in only at #27. This is not because ANY/A is a bad way to measure quarterback play — in fact, Winston ranked 2nd in the SOS-adjusted version of this last year, while averaging 10.2 ANY/A. He’s had a down year, at least statistically.
• Down at the very bottom of the list, in second to last place? Penn State’s Christian Hackenberg. It’s been a rough year for the Nittany Lions offense, as the offensive line is in shambles. Hackenberg, considered to be a possible first round pick in 2016, will need to put together a much better season statistically in 2015 if he wants to keep that dream alive.
1. Based on the results here. []
• Matt Mills

In CFBit may be important to take in to account rushing plays as well. You wouldn’t have to worry about counting sacks or sack yardage lost since it would get thrown in to the total yards. The weightings may not work out exactly (does a yard of passing equal the same as a yard of rushing? What about touchdowns?) but it could be interesting with all of the running college quarterbacks do.

• Chase Stuart

I hear ya, Matt. I always find it tricky to incorporate rushing stats for QBs, but I understand where you are coming from. It’s an interesting idea, and it’s also something ESPN does with its QBR.

• Have you tried the Washington Post for sack yards? I helped a friend research college stuff (I don’t write about college), and I remember WP having sack data.

• Chase Stuart

Thanks, Brian. That’s good to know, but do they have a full list that’s easy to manipulate to come up with things like ANY/A and VALUE?

• I’m tempted to call you Stuart, but I’ll pass ðŸ™‚

From what I can tell, no way man. The WP is good for small projects comparing a handful of players. I had to go there to get sack yards and then go to CBS Sports to get fumble information. I am hoping CFB Reference will be able to get the info, because I am super interested in doing college-to-pro studies.

• Chase Stuart

Ah, sorry. I’m the worst!

One thing that I am now intrigued by: how much control does a QB really have over his sack yardage lost per sack? Is that on the QB, or is that just randomness? Would we be better off using league average sack yardage in things like NY/A, which are supposed to be predictive?

Or, perhaps, the opposite. Maybe sack yardage lost is super sticky. I don’t think I’ve ever investigated this before, and I’m not sure if anyone else has, either.

• I looked into it a little when I was experimenting with estimating sacks and yards lost for older players. I didn’t notice a strong trend, but I wasn’t looking for one either. I’d be interested to see if there is any stickiness to yards/sack for coaches, since they can have such disparate schemes. I imagine the average Mike Martz QB probably lost more yards per sack than the average Andy Reid QB did.

• Red

Within a given season, it’s pretty much random from what I can tell (unless your name is Case Keenum, master of the 23 yard sack). But there’s no question that sacks are shorter in today’s NFL than they were in the 80’s and early 90’s. Back then, QB’s were almost always taking 7 step drops, so it makes sense that those sacks would lose more yardage.

• Rob Pitzer

As far as I can tell TD% above some fairly low threshold and INT% below a fairly average threshold don’t matter much, so ANY/A doesn’t really work as well for NCAA QBs. I suspect it’s because in college TDs are heavily receiver/offense/opponent driven, but haven’t really looked at that closely.

On the other hand, sacks are a stone cold killer for pocket QBs (Hackenberg’s 10% sack rate this year is a HUGE problem) but fine for out and out running QBs. Interpreting a high sack rate for “run-around” QBs like Rodgers and Romo are mostly just a giant PITA to interpret and I think you’d have to resort to film to really get a grip on it for players like them.

• Darnell

That link doesn’t take us to an SOS-adjusted version of this list from last year.

• Red

I’m shocked that ANY/A in college (6.1) is lower than in the NFL (6.3). Seems like every week there’s a couple 59-56 type games, so I figured passing efficiency would be off the charts. I guess with 120+ teams, you’re gonna have a lot of bad QB’s.
