For the second consecutive season, Breida topped 5.0 yards per carry as part of the 49ers' dynamic running attack while also having trouble staying healthy, missing three midseason games with an ankle injury. Once Breida returned, Raheem Mostert had usurped his spot in the pecking order, and Breida failed to get more than 12 snaps in a game from Week 14 through the Super Bowl. Breida received a second-round restricted free-agent tender early in the offseason, but he was then traded to Miami for a fifth-round pick on Day 3 of the draft. Heading into his fourth season, the 25-year-old remains explosive, having recorded the top speed of any ballcarrier in 2019 when he hit 22.3 mph on an 83-yard touchdown run in Week 5. His smaller frame at 5-10, 190, and durability issues likely will limit his workload with his new team, and offensive coordinator Chan Gailey's scheme will be a downgrade from Kyle Shanahan's, but with Jordan Howard around to handle the heavy lifting between the tackles, Breida should still do some damage as the lightning to Howard's thunder. The Dolphins did trade for Lynn Bowden just prior to the regular season, and the rookie third-round pick possesses traits as a gadget player and potential change-of-pace option, but Breida's job should be his to lose.
