In 2 of 3 seasons Zeke has been second in total yds from scrimmage. The one season he wasn't, he missed 6 games but still was a top 10 rusher on that season. Zeke in year 4 is still producing at a high level and is still among league leaders in many categories, despite our increased down field passing game.
Jones is in year 3 and hasn't shown that same level of consistency, in 3 seasons, he's only broken 100yds from scrimmage a handful of times. Recency bias, Jones played great in his last game, but that doesn't mean he can sustain a high level of performance. Zeke has proved that he can, going on 4 seasons, not just a handful of games. Zeke is a great RB, right now we don't know what Jones really is. Will he be a great RB or just a good one or above average with a splash day every now and then?
