I think the best evaluation of a coach is what the kids who play for that coach feel about them. Maybe not right now, but as time goes on. Lessons learned are not always immediate. Sometimes it takes time for a player to reflect on what they learned and the experiences they had. Funny thing about that is the bad experiences. These are sometimes where the most takeaways come from. With that being said. W/L is a big factor, player development, and quality of players. Attracting top talent is important, however retaining said talent is as well. Keeping parents happy should be so far down the list, it should not be a factor at all. Its also depends on who you ask. I am sure Org directors will have a different take then parents, then kids.
