Roger Goodell

When I met with the players the day before the draft, Melvin asked if I would give him a special handshake. He showed it to me and then we practiced one time. It was fun, glad I didn't screw it up for Melvin.

Thanks for your question, Mrs. Eisen!

We are proud of the work Rich does on the NFL Network. It has been gratifying to see the growth and success of the Network, which he is a big part of.

This rule gets reconsidered by our Competition Committee every year. We think we have a good balance between sportsmanship and natural enthusiasm. We want the players to be able to celebrate without taunting the opponents and casuing a retaliation.

I'd be interested to see how other fans feel: do we want more?

Thad, glad to hear that Reddit is so passionate about NFL football. Hope you all have enjoyed the season as much as I have.

We expanded our regular season series in London to two games this year. So far, we've seen the same passionate support for the NFL in London, based on ticket sales to date. If our game continues to grow in London, it would not surprise me if we had an NFL team in London someday.

No, the penalty will continue to include the 2nd round draft choice in 2013.

The game of football has always been tough and always will be. Even before the NFL was founded, President Teddy Roosevelt called the college presidents in to make sure that the safety issues of the game were addressed since there had been 17 deaths in 1905 alone. From there came the first and ten, forward pass and the inception of the NCAA. Since then, the game has flourished while sticking to the fundamentals of fair and competitive football. Our football coaches and executives wanted to bring the game back to the fundamentals of tackling and blocking. We have seen some of the best NFL football in our history during this season's playoffs. Hope we finish with another great one on Sunday.

I notice there are a lot of questions on socks. This is a matter initially judged by a former player at the game called the Uniform Inspector. It is part of our effort to look and act professional at all times. There is a standard fine for violations that our Football Operations department issues on a routine basis. This is a system that was put in place in the 60s and has served us well.

We're reevaluating all low blocks on defenders. I would anticipate that there will be changes in this area. These rules are studied very carefully by the Competition Committee, which is made up of GMs, owners and coaches, including with input from the players, and then voted on by the full membership. The reason they get such careful analysis is to make sure we understand the unintended consequences of any rule changes, and that they can be officiated with consistency.
