Hard to know what to make of this. Both Lockhart and Hogan are in a different league from the average NYJ clown at 345 Park.
Joe Lockhart was Presidential Press Secretary during the Clinton Impeachment proceedings and throughout the Starr Investigation, so anything that "heavyweights" like Peter King and Pal Salantonio can throw at him will seem like powder puffs compared to what he's had to deal with in the past. He is very well regarded in media/communications circles and he knows his way around the "real" media very well. His appointment is "overkill" for what the NFL usually has to confront in terms of media relations.
Cynthia Hogan is the more interesting of the two appointments (in her case, a promotion), IMO. She has worked for Biden for years, both in the WH and starting when he was Chair or Ranking Member of the Senate Judiciary Committee. She is already very influential in DC and will be more so when Hillary finally gets indicted and Biden jumps in to fill the void.
What they have in common is that they are both very good at what they do and have been in "war room" situations most of their careers.
Suggests to me that (a) the NFL will not be surprised if it loses the Brady Appeal and (b) that they expect a lot more blowback both from Labor on the Commissioner's power during the next CBA and from members of Congress on concussions.
