I'm one of those parents of a D3 player who has elected not to identify my son and where he plays publicly. So without naming names, except for recruiting and results, which speak for themselves, and game management, which I can observe and pass judgement on like anyone else, and I do, pretty much everything I know about my son's college coach I only know second hand, through the prism of my son's experience and retelling of events.
That said, the things I appreciate most about my son's coach are his communication skills, his support, and his ability to correctly prioritize the meaning of baseball at a high academic college. Coach texts and emails his players constantly, as a group and individually, and my son has shared a few with me. For example, his welcome letter to his incoming freshman was a classic in which he introduced the group to each other as future lifelong friends and wrote really eloquently about his expectations and the meaning of their efforts to excel on and off the field. Individually, he's been understanding as my son has struggled with health issues this season and he's mustered a significant amount of medical resources to help him. As for the prioritization - my son came from a successful HS program run by a guy who was a real hardass, so he was used to that, and used to winning. I don't want to put words into his mouth, but I think at some point during a frustrating freshman baseball season, he was wondering if his team didn't need need a coach would have his players running poles early on Sunday morning after a DH loss on Saturday. What he learned is that his college coach feels that grinding players down to get wins isn't worth it in that environment. He wants his team to succeed on talent and hard work, not on fear of getting yelled at and running poles when they lose, and he thinks that the players are already subject to a tremendous amount of stress due to their intense academic workload, and doesn't want to add to it.
That may not be appropriate for every college or every level, but I think it is for this one, and it's in keeping with a general theme of his that the players are men now who need to learn to take care of their own business, not be constantly told what to do by adults. The results are a work in progress but they are trending in the right direction.
