Dolphins' Projected Winners of Key Position Battles

Peter Joneleit/Icon Sportswire via Getty ImagesThe Miami Dolphins have some fascinating positional battles developing at the back end of their roster.

The stars are already locked into their starting roles, but some of their backups may not be decided until after the final preseason game.

Mike White and Skylar Thompson are locked in a battle to be Tua Tagovailoa's backup and a handful of wide receivers are fighting to stay on the roster behind Tyreek Hill, Jaylen Waddle and Odell Beckham Jr.

Defensively, the Dolphins have a breakout star at linebacker who could be vital to the team's success while the stars at that position work back from injuries.
