One thing Cardale doesn't get a ton of credit for is how well he avoided sacks against VTech -- or how hard he is to bring down.  Here was the interesting stat tweeted:

Highest rate of pressure P5 vs. P5 teams in Week 1: Auburn - 42.2% Notre Dame - 40.6% VaTech - 38.1% UCLA - 36.8% Nwestern - 35.9%

I don't know how ESPN gets those figures but for comparison, here is how all that pressure translated into sacks:

Auburn - 4 sacks
Notre Dame - 4 sacks
VaTech - 0 sacks
UCLA - 1 sack
Northwestern - 3 sacks
