Well, hopefully the coach was teaching the player to be able to play multiple positions, if not it may be a reason for finding a new coach... at the end of the season. As far as club recruiting goes I may be wrong but I think that cat officially left the bag, when HH explained earlier how his daughter ended up on her current team in the first place.
I'm not saying a player shouldn't show loyalty to a team, but at the end of the year the team essentially reinvents itself through tryouts... creating new expectations of loyalty for the next year. Some players may be replaced by the coach for not performing well on the field, some may be replaced because they decided to go elsewhere. At the end of the year some players may be leaving for another coach just because the other coach let's the player know ahead of time what league the team will be playing in, so the parents will know if they can afford it.
Yeah, it bothers me if a player's jumping to another club during the season, when teammates on a frozen roster are counting on that player to be there. It also bothers me if I see a lack of in-season loyalty from the coach to a player, as in a situation where a loyal player let's a coach know her intentions for the next year having no affect on her loyalty to her current team, and the coach responds by prohibiting her participation with the team for the remainder of the current year. What service to a 16-year-old is the coach providing there? Shouldn't we be expecting more?
A DOC at a club where I coached used to impress upon us, "Yes, we want the player to play soccer here for us, but more importantly we want the player to be playing soccer SOMEwhere." I don't believe he was talking about players leaving at mid-season. Pretty sure that would have ticked him off.
