Roger Goodell sees a difference between daily fantasy sports leagues like FanDuel and DraftKings and season-long fantasy football leagues the NFL supports.

Goodell said the NFL sees a "big distinction" between daily fantasy sports and season-long leagues, which he said are "an opportunity to enjoy the game." Fantasy football, Goodell said, is "not about making money.

"Season-long fantasy -- many people probably play here in this room -- it's for fun," Goodell said during a fan forum in Minneapolis on Sunday morning. "It's social. It's an opportunity to enjoy the game, and we encourage our kids to do it. They have clubs in school. It's a way to connect people, and we think that's a wonderful way. Daily fantasy's taken a little different approach. We want to make sure we understand how it would be done. We love people who are going to engage in the game and have fun with it. It's not about making money. It's about enjoying the game and enjoying the team, enjoying the players you pick."

Jerry Jones and Robert Kraft have invested in daily fantasy companies, but the NFL has maintained a public opposition to gambling.

"Daily fantasy is different, in the sense that it's essentially, the player picks whatever players they want," Goodell said. "They do that independently, and it's a matchup of those players. It really would be difficult to have that remote influence we are worried about than gambling in general. So I'm less troubled on that front. But I also want to make sure that, specifically our fans, when you play something, I want to make sure there are proper consumer protections. That's important for us."
