"I simply look at how quarterbacks have performed over their college careers in three key situations: against the top defenses in college football (the top 50 using S&P ratings via Football Outsiders), in third-and-long situations, and in the red zone. The first one is self-explanatory. While college defenses aren't as good as NFL defenses, you can still learn more about a quarterback against the better ones than you will against some team giving up 40 points per game.

As for third-and-long and the red zone, I chose these because they are situations that more closely mimic the kind of defense a QB would see on the NFL level. On third-and-long, a defense knows you're probably passing and is more likely to bring pressure. In the red zone, you have a lot less room to work with, which mimics the smaller windows a QB will have to throw into on the NFL level."

"While there's no set guideline to go by, generally speaking, if a quarterback doesn't score at least a 960.000 in this formula, you should be hesitant using a first round pick on him. As you can see, only two quarterbacks in this class meet that threshold, and Mahomes gets there by the skin of his teeth."

20 Zach Terrell Western Michigan 853.481 3,533 yards, 33 TD, 4 INT


Nathan's high score doesn't surprise me, but Brad Kaaya's next to last finish does. Nathan also scored higher on this list than Joshua Dobbs. Humm...

Also, Gunner Kiel scoring higher than DeShone Kizer is interesting. Although, I assumed that Gunner Kiel had long ago left the college ranks.

Kaaya being second to last is a surprise, but nothing I see while watching him says NFL quarterback. Impressive spot for Peterman.

Surprisingly, this goes with how I've ranked them since the season ended. I ranked mine:

1) Trubisky
2) Mahomes
3) Peterman
4) Watson

Like someone said above me, they should apply this to the previous years and see how they did.
 
Using a raw statistical analysis to rate a bunch of QBs who play in totally different offenses and leagues against widely varying quality of opponents and with widely varying quality of offensive personnel around them is, well, a crock of $hit.

Take one small example-Nate Peterman in Chaney's offense versus in Canada's. Red zone TDs were a scarcity under Chaney. They were virtually automatic under Canada.

Trained eyeballs are still the absolute most reliable way to evaluate any football player.

I'm confident that his #3 guy isn't the number 3 guy on the board, and he's likely not even going to get drafted.

No question he's not a first day guy, but he likely gets drafted in the late rounds. I've watched him play in person many times over the years, and I have never thought his arm strength or foot speed/agility is good enough for the NFL. You don't have to have a Matt Stafford or Brett Favre cannon of an arm, but you do have to be able to make all the throws, and I'm not sure he can--especially that deep out that is the measure of QB arm strength.

From how I read it, he isn't using the metric to rate the QB's in order. He is just saying if the guy isn't above 960 then its likely he isn't worth a 1st round pick. I could see that play out. Obviously the first thing scouts look at is arm strength. If the guy has a weak arm it doesn't matter what else he does well he will struggle in the NFL. Next they look at size. If your not 6'2 or taller chance of success are much lower. After that everyone has their own formula for predicting success. this is just another one but to me what he is saying makes sense.
 
As a side note, Nate scored a 33 on his wonderlic. That is a nice score and only bettered by Kaaya for the qbs(34)

Does the NBA use wonderlic?

The NFL barely uses it. There are still plenty of guys drafted high with scores in the single digits. That is remarkable to me because I can't imagine how dumb someone has to be to get a 6 on the wonderlic. They are like 4th grade questions.
