I'm sure that Seattle D is defending against this, but...

Goff hasn't played since his injury, hasn't thrown the football in real time...
So, how about McVay "schemes him" some quick-hit passes to allow him to find a little rhythm? No long patterns for the moment, rather quick look-ins to the TEs, a screen pass, etc.?
Yes, yes, I know, it's far easier to do this from the comfort of the Barco Lounger than in real time...
