No he didn’t. That’s a double move route and it came from the blind side because the LT made the worst possible effort to block him. That wasn’t on JG at all
I've never seen anyone playing this long as a starting QB that doesn't realize you have to step forward in the pocket. Of course the next blitz he sees early will be the first. You have to, at this point, expect the OL is going to whiff out there and plan for it.
