It was a running joke in fantasy football circles and on Twitter that the reason Kenyan Drake has yet to become a NFL feature back was because Adam Gase had a vendetta against him. Why else would Miami's former coach play Frank Gore, 35, over a then 24-year-old Drake last season?

Yet for the third consecutive offseason -- this time with a new coaching staff -- Drake is expected to be featured in a multiback offense where the hottest hand could lead the backfield on any given Sunday.

This realization is less a condemnation of Drake, who is a great talent with probably the most explosive big-play ability on the roster, as much as it is what Miami believes Kalen Ballage can do with increased reps.

As of early August, neither player should be projected to be the Dolphins' three-down feature back in 2019. The backfield could be like it was with Gore and Drake in 2018.

But that's all up to Ballage, who is the X factor in this equation. Dolphins running backs coach Eric Studesville says none of Ballage's potential will matter unless he proves it on the field, though.
