There's a difference between pressuring a QB so it disrupts a play and not being athletic enough to make a play. Wiffing on sacks so the QB can step up and make a big play is not the same thing as pressure.
I'll have to look back and see. I think Gangwish gets a lot of undeserved negative attention. I don't think its really fair. I know the plays he missed on, damn it was close. He almost had a few good sacks there.
Totally admire the passion and dedication Gangwish brings, but we need him to finish plays in the backfield. Closing speed and finishing plays are something that set great DEs....like a Wistrom or Gregory....apart from the rest.
