By the time the 49ers season is over, Arik Armstead's jersey could end up threadbare from all the belly rubbing.
Every time the defensive lineman registers a sack, he strokes his stomach in hungry-man fashion to underscore how much he likes feasting on opposing quarterbacks. And he's never had a bigger appetite than this season.
On Sunday, he planted Carolina's Kyle Allen for his fifth and a half sack of the year, giving him the team lead over rookie phenom Nick Bosa, who's something of a sack machine himself.
Now even fans are getting into the action.
