I'm pretty sure RR commented before the season started that Gardner's red shirt wasn't going to be burned by Gardner getting a couple of plays/game. At this point though, that's what it's turning out to be. So does RR make a concerted effort the next couple of weeks to get Gardner in the game during the first half? I'd like to think he'll be getting into the game during the 4th quarters in mop up duty.
Robinson's been out of the world so there's been no reason to take him out in the first two games. However, to burn Garnder's redshirt by putting him in for one or two plays is frustrating. Once the big ten season rolls around there might not be to many games where Gardner can get meaningful snaps if Robinson doesn't get dinged and have to come out.
