I'm not sure it's the same as BTC.
I was told by a really good source the other day it was petty competitiveness and personality clashes that spiralled out of control. And Coogan is a very good running coach - he's not an HR manager/character coach.
Stuff like who leads what reps at what pace. An athlete running "too fast" at the end of a session of 800's making an athlete coming back from injury not quite as fit "feel bad". It's funny because on the other thread I said that I thought this was exactly what it would be and some people got upset about that - within an hour I had a text from someone saying this was exactly what it was. Valby comes in to the group straight from college and is making at least 2-3x what Mackey and McLean are making - there is no way there isn't friction.
As a brand it/pro group it isn't easy, especially if you have you have the athletes training together, especially on the track. Because then it really needs to be a team exercise but running ultimately is a single, selfish sport. If you had a business and you were assembling a team, you wouldn't choose people with the exact same personalty types and strengths to work together, also knowing they need to compete together. But as New Balance, like other groups, you want to have the best and highest profile athletes and as Coogan, you just get told who you are coaching.
Human nature is why NB Boston is teetering right now.
