At his annual Super Bowl news conference on Wednesday, the NFL commissioner was grilled on two hot topics that have put the league under heavy scrutiny: racism and discrimination in hiring. There were other issues that don't shine a positive light on pro football, including threats to the integrity of the sport.

A week after former Miami Dolphins coach Brian Flores, who is Black, filed a lawsuit alleging both racism in the league and being offered money by team owner Stephen Ross to tank games, Goodell vowed action on several fronts.

"We won't tolerate racism. We won't tolerate discrimination," Goodell said. "I found all of the allegations, whether they were based on racism or discrimination or the integrity of our game, all of those to me were very disturbing. They are very serious matters to us on all levels, and we need to make sure we get to the bottom of all of them."

That begins with the NFL's poor record for hiring minorities as head coaches. While the league has made progress with other jobs, from general managers to coordinators, the most visible representative of a franchise is the coach. There are five minority head coaches on the 32 teams, two Black, one biracial, one Hispanic and one Lebanese.

Asked if the process is flawed, from how interviews are conducted to who might be conducting them, Goodell said the league already is looking into that - whether it involves changes in the Rooney Rule that requires interviews of minority candidates for coaching and executive jobs, or a new rule entirely.

"I think that's the core of the message that we've been talking about here is, OK, we're not having this success we want with head coaches," he noted. "How do we evolve that rule or do we have to have a new rule? Do we need to figure out some other way of being able to achieve that outcome? And I think we're not going to rest until we find that and we get those kind of outcomes that I think are mandatory for us."

Flores' charge of being offered $US100,000 for each loss in 2019 to get the Dolphins to the top of the draft is being investigated by the league.

"And when we know what those facts are and the impact it has on our game, we'll deal with it very seriously," Goodell said.
