BLOOMINGTON, Min. – NFL commissioner Roger Goodell had his annual press conference at the Super Bowl on Wednesday, and touched on a variety of league-wide topics.

Here are some of the main takeaways from that session:

1. What is a catch in the NFL anymore? Goodell is hoping that question becomes a little bit easier to answer this offseason. He wants to take a fresh look at the rule with the competition committee this offseason, and said the goal was to "start over" rather than adding or subtracting from the current catch rules.

"There will be a lot of focus on going to the ground," he said. "We have a great opportunity to get it right."

2. The NFL had even more replay interruptions this season vs. the previous year, and it's something Goodell would also like to take a look at and try to improve if possible this offseason. The league will look at replay in a way that will ensure correcting obvious mistakes, but also make sure it doesn't interrupt the flow of the game. Could we see a time limit on reviews?

3. A bit of breaking news to come out of the session is that the Los Angeles Rams will host the Kansas City Chiefs in a game in Mexico City next season.

4. The NFL has a new five-year television deal with FOX to broadcast the league's Thursday Night games. The NFLPA and some of its player members have raised concerns over the years about player safety as it pertains to playing those Thursday games on a short turnaround. Injuries were slightly up in 2017 on Thursday vs. other days of the week. Goodell said he has spoken to NFLPA executive director DeMaurice Smith to address the short weeks heading into those Thursday games.

5. Goodell said league owners want to stay in the Carolina market. The Panthers are currently up for sale after owner Jerry Richardson was alleged to have engaged in workplace misconduct and sexual harassment. Those allegations are currently being investigated by the NFL.

6. When asked about current NFL players' frustration that former 49ers quarterback and activist Colin Kaepernick hasn't been given an opportunity to join a roster, Goodell said it was really up to the individual clubs who they sign to their roster. The league doesn't plan on getting involved.

7. Loosening the celebration rules was very good for the NFL this season. Lions players certainly enjoyed the greater freedom. Remember Rock 'Em Sock 'Em robots and the kick line? Goodell said it achieved what the league wanted: To allow players to express their passion and individualism.
