This story talks about how both Saqon runs and his own involved Hurts setting the play (and coverage with Jurgens). Just did not happen on the safety
"it starts with Jalen to get us in the right play," Siranni said.
I think there's probably a point where the coaches have to protect him from himself/remind of his limitations if he does in fact have them, but their general approach has been, if he's playing, he's playing like he always does (the concussion recovery included).
I would imagine Hurts and Mitchell will be LP on Wednesday and FP on Thur, or maybe there will be a rest day. But they are playing. Not sure Book's status matters, he's buried on the practice squad in case any of the other three gets injured, not because any of them are injured (he was on the roster when that was the case and even then that still took two injuries).
