I don't know you or your situation but you asked, so heres my 2 cents worth. Positions are earned, they are not given to anybody, I would say that someone has out worked your daughter and took her position. Instead of asking on here what she should do, tell her she needs to work harder and earn the spot back, neither you or her would be happy if a coach just handed out starting spots because it was hers last year. I know from experience, questioning a coach about playing time is the final nail in the coffin. Just encourage her to continue to work hard and make an impression that she is willing to work hard to get her spot back. Don't let her or yourself become a cancer to the team, or everybody loses. Again, just my 2 cents worth.
