I expect a route, maybe two, per game where Josh and his WR aren't on the same page. I hope they fix whatever the bad reads were by both in last weekends games.
Diggs needs to finish his routes, hard, and let the officials call their games.
The only other suggestion from me, and this doesn't need to be said, because I know our WRs know this better than anyone - when Josh is scrambling, find the open space. All of you, find the open spot on the field. Josh will find you.
Oh, and one more via edit for giggles. Diggs says you can't catch Josh in your chest, because it hurts, especially when it's cold. You gotta use your hands
