If the leaders of my team came to me and expressed concerns about a new player, I'd respect that and be loyal to them. I assume these team leaders like to win just like I do. If there are other agendas, I think I would sense it. They wouldn't ordinarily speak up unless they found a player to be particularly abrasive.
Also, in travel ball, I consider the team to be 'ours,' not mine. That is, it's a group of coaches, players and parents that all have a little say in the philosophy and direction of the team. Obviously, the coach has more say than anybody else, but part of my job is to deliver a certain positive experience for them. So the players have more say on a travel ball team than they would in high school or college, where the coach is working for the school. In travel ball, to some extent, the coach is working for the parents and players. So their concerns are very important, IMO.
