Possible they'd be cleared tomorrow/this evening... which would make them available, but unlikely they'd contribute more than a handful of snaps.
This. They can certainly be used stuationally, even if all they get is the Friday walkthrough practice.
There's no reason why KVR can't be thrown out there in a strict man-to-man on 3rd down or in a Cover-4 on a 3rd and long. Mentally, there shouldn't be anything unusual thrown at him in those situations.
Same thing for Ishaq if the coaches think he can be utilized rushing the passer on 3rd and longs or run-stuffing on a big 3rd and 1 or 4th and 1.
Ditto for DD if the coaches want him to run a Go route to push a safety to his side of the field, or are running a simple WR screen play.
Probably too much thinking going on with Safety, and I think they need the reps for ST play for the coaches to trust Hardy/Moore after one day of a walkthrough practice.
