From what I've heard is Ritz is pretty against a big team of people competing with each other for global teams.
So now for the men you have the 1500 group will have Hoare, Nuguse, and Romo representing 3 different countries. The 5k group Beamish, McDonald, Klecker representing 3 different countries.
If you bring in Wayment (who probably preferred to stay with Taylor) and Steelman you would have 3 US steeplers competing for 3 spots. Not the easiest way to add numbers to global teams.
I had a friend who was in talks with joining OAC after graduating last year, but Klecker was their US 5k/10k guy, and Ritz wasn't super interested in adding another.
