like it or not, the NFL does have a problem with racism. Their race norming program is one of the racist things you'll see a company do. with that said, Flores' is reaching really hard with some of his claims.
Flores claims that his refusal to tank in 2019 caused him to get fired in 2021. There aren't a lot of coaches out there that are going to get a fourth season without a single playoff berth.
It also sounds like the Dolphins had three finalists for the job, but they had an idea who they wanted to hire. Had nothing to do with race since the Dolphins had already fulfilled the Rooney rule requirements before Flores.
also his claim that this isn't just about football, this is about all of America and all industries tells me that he's in stage one of a grift.
