Take those numbers how you will, but good gravy those are some really really poor QB stats. Purdue was no doubt the best with Nebraska coming in second with Martinez at the helm.
For reference only one school in the Big 12 had numbers like this and it was KU. Also, Casey Thompson threw for 2113 yards at a 63.2% clip, 24 TD and 9 interceptions with a 154.7 rating.
As far as whether Petras is third best.. I honestly don’t know. Looking at those numbers, maybe? Lol but that’s really not saying much at all.
It’s only because of elite defenses. Or something.
