OK, I have some examples, however, I consider myself a fair coach.
Suzie A - ACL surgery, rising senior.. couldn't tryout. Received a number, showed up to the tryouts did work with the trainer, helped me sort uniforms. Her number is listed under Varsity pending injury clearance and ability once healthy.
Suzie B - rising junior, not a bad cheerleaer, no handpsring, but this just started recently, we had it since 7th grade and now nothing.. mental block of some kind, had terrible tryout. Varsity game, competition consideration pending backhansdpring. (note I said consideration)
Suzie C - rising sophomore, really good cheerleader, weak stunting and needs work, NO TUMBLING. All rising Sophomores have at least handsprng series or tuck. JV.
Suzie D - rising senior, never misses a practice/event, always 15 minutes early, last to leave after mats are rolled up. Dr note, very sick for tryouts, was not in school. Met up with me Satruday afternoon to show me material and do her skills. Varsity, considered for varsity competition.
Suzie E F G H I - Rising juniors do not have the skills, JV
I get politics and last year I took 2 rising freshmen on varsity, they are like 80 pounds each, but they both had tucks + and we graduated 2 flyers and the upperclass flyers weren't ready to take those roles... I use judges scores for the obvious bubble kids and also back-up if there are issues and what is funny, is the scoring is always right. Always exactly where we mentally placed.
