The Jaguars have a good running back in Leonard Fournette but runners take a lot of pounding in the NFL. The team needs at least one other back to take some of the pressure away from Fournette and provide more versatility.
The Jaguars have five running backs on their current roster: Fournette, Ryquell Armstead, Devin Ozigbo, Devante Mays, Taj McGowan, and Jeremy McNichols. In 2019, Fournette was the one and only back with significant playing time. It was a miracle that he survived the season because he spent a great deal of time running into a wall.
