The key for any coach is awareness and setting out and managing too, expectations for players, parents and coaches...
Watching intently during ALL team activities is a first step. A lot of teams / coaches struggle with providing a complete training program for their athletes or themselves that can create problems.
At the HS, College and an inner city programs I coached with I would use the softball school lessons we developed back in the early 2000s to help players identify behaviors that are or could hold them or a teammate back.
Lessons on personal relationships, balancing sports with life should all be part of the softball experience not just the fundamentals of hitting/fielding but the addition of the fundamentals of being a team player and enhancing ones softball IQ in a variety of areas.
If you are a parent that finds yourself on a team where behaviors are not checked, team bonding and team building are not part of the program or the coach may just be in over their head its important that you do not tell the player to suck it up or just ignore it. These behaviors will get worse if not addressed and that includes social media as well as team activities.
It is always advised to inform the coach and parent of any concerns. In most cases problems can be resolved quickly if not left to build. In rare cases a family may chose to go another direction if the differences cannot be reconciled. In even rarer cases players will walk away from the game at all levels.
