QBs 18 for 19 245 yards, 5 TDs, 0 INTs
Defense only allowed 34 yards and 0 TDs, 4 INTs
These stats were probably "alternative facts". Meaning the QB stats were compiled and reported against the 2nd, 3rd, and scout team defense and the 1st team defensive stats were compiled against the 2nd, 3rd and scout team offense. They didn't combine them so they would look better. They probably didn't do any 1s vs 1s either.
I could most definitely see Franks carving up the 2nd team secondary since they probably had scout team and walk on players on it since they have zero depth.
