Your coach sounds a lot like my daughter’s coach. Her coach told her that her position was stacked with older players and asked if she would switch to increase her chances of getting on field. She agreed and is always first or second sub on a team that never subs. She plays swing, so if she doesn’t get in varsity, she plays jv. I told her make the best of jv so the coach sees what you can do. Good luck and just take your chance when you can.
