Josh is an elite athlete with a contract because he ran 2:13 less than a year ago. Check the ranking and see where that places him on the U.S. list. He also holds an American record, set less than a year ago - "bogus" distance or not, it is what it is. Ultras have popularity they didn't have years ago.
Josh is also highly likely going to get 5 (or more) Olympic Trials qualifiers (a men's record) - a title I wanted before my achilles claimed me.
So in summary:
Quality runner - Ranked, record holder.
Longevity - Been in the game at a high level a long time.
Lastly...hey Josh! Got your back on this one and you know I've always envied your success (and attention!).
To tie this into Hall. Hall: Get back to the track then, return to the marathon. That's the only fix you'll need, no matter where you go, this is what ails you. Strength and speed are related and feed each other. A sub-13:00 will give you 2:05 (You so can run the fast if you focus on it).
Also, groups work. As much for your mind than your body. You just need faster training partners training for the same races.
