Hyde is the superior talent to Johnson right now.
They are both averaging almost exactly the same carries at right around 3.9 YPC. The difference is Hyde's touches have been increasing into the double digits, whereas Johnson has had 6-7 carries the past 2 weeks. They both have scored the same amount of TDs. Johnson did appear to be used more in the passing game and may have some boom or bust RB3/4 appeal in PPR leagues.
Im not even sure Moreno comes back and takes the starting gig 100% with how well Miller has been running. If you have your mind made up and which to drop I would ask yourself this.
Will Johnson make a turnaround and start being more productive then Ivory? Also, consider how much in shambles the Jets offense is right now, and couple that with their depleted secondary and you get situations like what happened today. Even trailing by 30 points, Johnson was only targeted 1 time in the passing game and he turned it into a whopping -2 yards. As always, Ivory could get hurt, and then technically his workload would increase, but I just haven't seen any playmaking ability as of yet.
Hyde on the other hand is younger, less tread on his tires, and plays for a run first offense. He is the safer bet.
