IMO I would never jump mid season if I was unhappy and it called for it I would take her off the team. My older DD has had a few head coaches call her after nationals are over and tell her "she should come to their tryouts" but never mid season
So many things not being considered here when it comes to switching teams mid-season. Remember, A-ball coaches almost universally have a disdain for team jumpers.... so there must be good reasons, right?
A couple of things not mentioned:
1. What does it do to the remaining girls on the team that is being left behind? How do they feel when one of their friends leaves them? If she is a top player, do they start losing more games?
2. What does it do to the girl who is leaving? Does it make her think she can just quit anytime things don't go her way? Does it make her feel bad about leaving her friends? Does it give her anxiety about making new ones? Is she afraid she won't get playing time on the new team or that the girl she replaces in the lineup will hate her?
3. What does it do to the girls on the team being joined? A team with good chemistry and happy families absolutely will be affected by the new girl. If she is good, she will take someone's spot and a previous starter (read: happy family) will now be struggling for playing time (read: unhappy). If the new girl isn't quite good enough to take a starting spot, then her family is still unhappy. You will have more unhappy families on the new team than you had before, no matter what happens. No good can come of this!
For me as a TB head coach, I (and most of my peers) see team jumpers as cancer. Why would I want a girl on my team who has proven through her actions that she (her family, more than likely) only cares about herself and has no problem flinging a couple of dozen other girls (her previous and new teams) under the bus so she can get what she (they) wants?
I want girls who practice the mantra of "team first" to play for me. The is no way in hell I am taking a girl who doesn't give a flying you-know-what about the girls on her previous team (she abandoned them!) or the girls on her new one (she is going to make some of them unhappy and upset the chemistry of all of them!). Selfishness in the form of disdain for your teammates has no place in team sports and will get no place in my dugout.
You are absolutely right. There are exceptions. Couldn't agree with you more. Hell, I even know of a few myself. Great kids with great families in bad situations. There is even a girl I would take right now although she wouldn't be much of a help to my team just because I like the kid so much and her family is awesome. She is on such a lousy team that she is starting to not like softball and I really feel for her. I would rescue her in a minute if her parents asked. I don't think anyone would call her a "team jumper" for leaving this team, but they have decided to stick with it because she made the commitment.Some very good points and I will agree with this 95%+ of the time. But I think there are exceptions. Just my opinion.
