Ross told Adam Beasley of the Miami Herald,
“My position today was that we as owners and as a League owe it to fans to do everything we can to stay in the communities that have supported us until all options have been exhausted”
When we look at Miami and the landscape in terms of their market, they are a glamor franchise. Miami is a market where free agents want to come to and I don't think Ross likes the idea of having another glamor franchise in the NFL.
This leads me to the most powerful individual in the NFL, the Dallas Cowboys owner Jerry Jones. Jerry advocated for the Raiders move to Vegas because San Antonio was another rumored destination and many Cowboys fans are in San Antonio so that would take a lot of that fan base away. Plus, the
Cowboys are the most popular team in Texas. Jerry is a businessman so he knows that if the very popular Raiders move to Texas, that is bad for business.
