I liked the way he describes "on-target rate" and "improvisation plays." Beats a superficial look at completion percentage, which can underrate how a QB performs under duress. An excerpt below.

First, O’Korn was exceptionally accurate for a backup quarterback. His on-target rate (see previous versions of this story for more on this) was 22 for 29 (75.9 percent), and he targeted 10 different receivers. While a couple throws waffled, both figures are better than Speight has done this season, and show that O’Korn has the ability to play like a starter beyond potential beginner’s luck.
But as I watched, another development arose that could bode well for Michigan. I pegged O’Korn as 7 for 8 on-target in what I will call “improvisation plays.” These are when the play broke down, the pocket collapsed or something else happened that forced O’Korn to work on his feet. That’s an incredible rate at which he can find someone open under duress, and might not be sustainable. But O’Korn’s improvisation kept Purdue’s defense honest, got more players involved in the passing game, and allowed the Wolverines to solidify momentum in the second half.
While this story is not meant to focus on intangibles, O’Korn’s dodgy approach may have rallied the offense around him. Having seen the previous games on film as well, a rewatch of Saturday looked like a sports movie after the coach tells his struggling team to just have fun or return to their roots in the championship game.
