That might just be JaMo's speed. Goff threw it to a spot, and JaMo likely got there faster than Goff thought he would. Not the first time we've seen him outrun Goff's arm. He had a drop at one point (can't remember when) where the ball was thrown behind him... again, I think he just got to a spot quicker than other Lions receivers would've. The dude is fast, like insane Randy Moss fast. He and Goff need to get their timing down (hopefully they're putting in the work)
