Maybe we are splitting hairs here but what makes Chubb a potentially elite runner is his elusiveness. Most people make the wrong application of elusiveness and apply it only to guys who can juke, etc.......but Chubb is otherworldly at beating a defender 1/1......wether that is through speed, power, patience, whatever. He just brushes guys off 1 on 1. That Ravens game was an absolute clinic.....he ran over people, he ran through arm tackles, he ran by guys when he had a lane......if he stays healthy, his combination of speed and power is unrivaled IMO, just as a pure runner. I think you can argue other guys are more valuable because Chubb is only a 2.5 down back......but if I need 2 yards.....or I need to ice a game away and a run play needs to be called, I want Chubb taking that carry.
And when Hunt comes back, we just have an embarrassment of riches at RB.
