Not that I'd ever want to be critical of HoFlynn but he didn't go against much of a DL when he played the Lions so who knows what will happen against a decent team.
Well obviously since Detroit DL ranked 10 in sacks. You are right that is not Decent at all. I mean it could be worse like packers 27th ranked.
Regardless, HOFLynn does not rely on others. He makes others.
