For whoever has been to a DA tryout, did they seem to be looking for technique or physicality for the most part? If I'm being honest with myself, my daughter would not make DA if they are prioritizing physical, and I am aware that many clubs already do this. She is rather small and not very fast, but her technique is what has kept her a starter in her elite club and a participant of the national training they do once a month. I don't know if her skills will cut it this time though, being that the DA teams are of combined age groups.
Many variables regarding your inquiry: your dd position is significant regarding speed. If she plays left/right back, she better have afterburners and stamina. If she plays mid, does she get knocked off the ball easily? Physicality is not only important during the game but also in recovery. DD style of play-does she release the ball quickly or dribbles into trouble ( bigger girls will knock her around)?
