My issue with the Rooney Rule

"The interview process was a sham because they already knew who they wanted in the first place"

Well, they are just following the rule that is in place.

If a team has their eyes set on a certain person, they have every right to hire him and him only and not even consider anyone else.

Why are folks acting as if this something new? Companies do it all the time. They interview candidates to fulfill a quota knowing full well whom they are going to select for the position. This is no different.
