Gallette had similiar pass rush numbers to Will Smith in just 301 snaps compared to over 1,000 and ranked 19th out of 109 graded guys, not exactly comparing poo to poo.
Stop trying to spin this like it is not a bad loss for the Saints. Your defense was terrible. Even if Smith was getting old, he was a still starter and going to play an important role on the team.
Nobody is scared over Gallette or Wilson as an edge rusher. Actually nobody is scared of anyone on the Saints defense. They are likely licking their chops over the prospects of facing them.
