Voluntary veteran minicamps are, on the surface, a small part of a team’s offseason preparation. But the process can have a major influence on who will and won’t be in position to compete for a roster spot moving forward. The Dolphins have decided based on their first 2016 minicamp to move on from five players. Gone are defensive back Damarr Aultman, receiver Tyler Davis, receiver Robert Herron, defensive tackle Robert Thomas III, and linebacker Terrell Manning. Herron was a sixth-round pick of the Bucs in 2014, and Manning arrived to the NFL in 2012 as a fifth-round pick of the Packers. All teams may have up to 90 players in the offseason. Most teams will be adding 20 or more rookies in the next few days, between the draft and unrestricted free agency.
