Quarterbacks aren't the only footballers competing for a starting job in Miami this summer. The running backs are getting in on the action, too.

While Ryan Fitzpatrick and Josh Rosen go throw for throw in red jerseys, Kenyan Drake and Kalen Ballage are working out who will enter the season as the Dolphins' top back.

Drake is Miami's leading returning rusher (535 yards in 2018) with Frank Gore out the door and was thought to be the starter coming into 2019. But the second-year Ballage, who averaged 5.3 yards per carry last year, has played with the first team through two days of training camp practice, per multiple reports.

It's still early in the summer and things can change, but starting Ballage ahead of Drake, who's entering a contract year, would be surprising. It's more likely the two split snaps come September. For what it's worth, neither back is worried about his status as the starter at this point in the season.
