Per Adam H. Beasley of the Miami Herald, Dolphins players "would revolt" if the team trades the 25-year-old before the start of the regular season.
Tunsil's name has come up in trade rumors recently, but Aaron Wilson of the Houston Chronicle reported Miami won't include him in a potential deal for Houston Texans outside linebacker Jadeveon Clowney.
Beasley did note if a team like the Texans blew the Dolphins away with an offer, "like Clowney and premium draft picks" for Tunsil, they would at least have to consider it.
Armando Salguero of the Miami Herald reported in January that the Dolphins embraced a tanking philosophy during the offseason and want to stockpile picks for 2020.
Per Pro Football Focus, Tunsil had the best season of his career in 2018.
Tunsil was Miami's first-round pick (No. 13 overall) in 2016. The former Mississippi star has two years and $12.5 million of base salary remaining on his rookie contract.
