"That's a little bit counterintuitive to the experience we had [in the past]," Goodell said. "Whenever we make a change like that, we want to look at the positives and negatives and what might be the unintended consequences.

If we're not doing that, then we want to make sure we understand why and what else we can do to effect that."
