No idea what Tucker's injury is, but I would be very careful with him the remaining games. No reason to give him 20 carries a game the rest of the way. I really like him as the starting back next season. My concern is the injuries. He's a physical runner and unfortunately he will get dinged along the way. I don't see a reason to force him on the field (which of course we won't) for meaningless games. Especially since Lutz appears very capable. Throw in Pierre for 10 snaps here and there.
My positive from this season is Tucker by far. Followed up by Garrett Williams, and some of the young defensive players.
