It's also a large presumption that Ingram would have gotten to 100 or scored since he's only managed to average 4 yards per carry in 2/7 games this season and hasn't had a 100 yard game in over a year.
Sunday will also mark a full calendar year since Ingram ran the ball 20 times in a game. In that year, he's averaged about 11 carries per game.
Ingram is a back that wears down defenses, he's shown it time and time again in his career. But for whatever reason, Payton refuses to give him the ball 20-25 times a game.
