I've brought 3 people into HBD. 2 of them quit during coach hiring. I don't blame them.
Coach hiring sucks. Worst part of HBD. It's time consuming. It's no fun. Nobody knows who any of their coaches are. We have no idea what we're bidding on, and never will (unless the new owners publish the algorithm).
I believe Mike, after 100+ HBD season, doesn't spend much time on coaching. For 95% of HBD GMs, it's all about checking in every 4 hours. That sucks.
Who's the better coach? Hitting Rating of 60 with Patience 60, or Hitting 50 w Patience 80? Then add the other ratings. It's not possible for anyone who does not have hundreds of seasons and spends hours running math models to every have even an educated theory.
Make MinL and ML coaching a budget, like Training & Medical. We get what we pay for.
There are a lot of reasons HBD is struggling to survive. Coaching hiring is high on the list. HBD would have more customers if there was more fun, more strategy, and less time wasting stuff like coach hiring.
