Are you just trying to find something to complain about?
Goodell has successfully managed the NFL into becoming one of the worlds biggest brand names and easily the biggest deal in American sports.
As for personal conduct policy and those TV timeouts, you can place those ones squarely on ESPN. In fact, I don't even know how the TV timeout gig has anything to do with Goodell. The producers approached the coaches. The commish was never brought into it. I have no Earthly idea what it is doing in a Roger Goodell thread. And for the personal conduct policy, it clearly is based on the NFL's image. You may disagree with it, but the millions upon millions of people looking for family entertainment value that constitute that fringe viewership that keeps the NFL growing, they like it.
This helmet to helmet thing is a big deal. Lots of players are out with head and neck injuries right now. Lots of guys already leave the league with serious issues in their knees, ankles, shoulders, etc. but this is effecting the long term mental wellness of a lot of guys. Even after just one severe enough concussion, you can lack the ability to operate the same way on a day to day basis. It gets worse -- do I need to post the link of the Rutgers kid who just got paralyzed from the neck down? Guys have been getting bigger, faster and stronger on a near-exponential rate since the days of true smash-mouth football. Put today's NFL bodies in the games of the 60's, 70's and 80's and I would guarantee players would be getting killed. The improvement in safety equipment has also made today's player more willing to use his body as a weapon on the field.
You very clearly seem to be behind the players on all the issues; as am I, they are the ones who the people come to see play every Sunday. But you simply can't have it both ways on the 18 game issue and the hitting rule (which, as explained numerous times on ESPN, has been in place for some time now). Players ask the NFL to not add two games to the schedule for the sake of their bodies; the hitting policy is there to accomplish just that as well.
Some of us are going to miss the NFL of the days of old, but that game as we know it is dead, and rightfully so.
