When Riley is delivering a blow when running out of the pocket or on designed draws, etc. His body is prepared for the hit. It is when he is hit in a vulnerable stance or when completing a throw that he was injured - twice this year. He waits for the play to develop and in some cases, stays in pocket amidst the pressure. Prefer that he scrambles around to avoid the big hit but also believe that the OL needs to hold their blocks longer and WR to create better space between them and DBs. WR can't have plays taking long time to develop or Riley may get hurt while hanging around in the backfield - just take off if no play is there.
Lark is probably chomping at the bit to play as it is his last hurrah - he will be prepared to fill in.
