NFL commissioner Goodell 'never satisfied' with officiating
Commissioner Roger Goodell conceded officiating in the NFL has room to improve, but also said the league's rules needed to be clearer.
Speaking on Wednesday during his his annual State of the NFL press conference ahead of Super Bowl 52 in Minneapolis, Goodell also touched on the controversial catch rule.
"I'm never satisfied," said Goodell regarding the standard of officials. "We can always get better. The officiating can get better and so can all of us. I think the officiating is outstanding."
He suggested the catch rule was being implemented correctly, but admitted it may need tweaking.
"What we have to do is find a rule that fits what we think should be a catch," he said. "I would like to look at the rule fundamentally from the start.
"There will be a lot of focus on going to the ground. We have a great opportunity to get it right."
The 58-year-old revealed reviews will also be revisited, with an increase of replay interruptions this season potentially damaging the entertainment value.
