It's wild to me that, given all the WR injuries in the NFL, Michael Thomas still can't get a shot?

None of his teammates has said that about him. Care to elaborate as to why you think that?
A) Teammates don't hire people. Owners, GM's and coaches do.
B) Said owners, GM's, and coaches likely see all of the negativity and drama that MT puts out there on social media, and don't want to bring that attitude and distractions into their teams.
