I don’t know these coaches, as I don’t follow the NFL all that closely. But I would tell who was black and who wasn’t before I even looked.
Frank Reich is a good coach.
Frank is most famous for being the backup quarterback to Jim Kelly and the Buffalo Bills in the 1990s. He orchestrated the largest come from behind victory in NFL playoff history.
The Bills ended up beating the Houston Oilers in the AFC Wildcard game.
He also was a very good college quarterback at Maryland.
He was always very cool under pressure.
