With Morgan only playing against Rice, Kelly and Van Gorder have to be at least considering a redshirt, until other issues at linebacker indicate otherwise.
Again, as others have noted, we seem almost to be using a nickel as our base defense --- that means Jaylon plus one other is who we need. That is usually Schmidt, or Onwualu, or Councell, or even Martini. AND the Tranquill/Hill package erodes significant reps and alters linebacker arrays too. MAYBE we won't need to burn a year for Morgan this season, particularly if Kelly/Van Gorder think that Grace will be able to thump at least half the season.
Of course recruiting success might play in this too. Perhaps a couple of studs still out there pop, and Van Gorder says: Coach I don't need to separate Nyles from the guys we've got anymore eligibility-wise. Kelly seems to not think like this [always saying he'll play the best guys we have to win the game today without regard to seniority or redshirting], but if Van Gorder thinks he has enough "winning guys", who knows?
My instincts say that Morgan likely plays, but mainly on special teams and at game-over time [barring injuries]. Kelly, despite what he says, does seem to worry a little about certain kinds of kids who can't handle disappointment. [I believe that a certain second team QB may be such a case]. If Morgan has any of this in him, then he probably won't be redshirted. Of that I know nothing.
