Pittsburgh Steelers coach Mike Tomlin was “disappointed” by the “lack of diversity” in the recent round of NFL hires for coaching positions.

“I think the numbers speak for themselves in that regard,” Tomlin said of the number of minority coaches, the Pittsburgh Post-Gazette reported.

Tomlin added, “It was a disappointing hiring cycle for someone who watches it like I do, knowing some of the deserving men I do who I thought should have gotten an opportunity and didn’t.

“But we’ll continue to work and fight for equality and opportunity,” Tomlin said.

Still, the National Football League currently only has three black head coaches. It is too few, as far as Tomlin is concerned.

“We’ll continue to fight, not only in terms of head coaching searches but maybe other areas of the profession as well,” Tomlin said.

“I know there’s some discussions in the offseason regarding some of that,” the coach concluded.
