I know a kid around these parts who was cut from a certain powerhouse team last year as a junior. Great kid. Loves the game. Loved playing for this team on JV his first two years. Was broken hearted over being cut. His (extraordinarily hot, but also hot tempered) Mom swore up and down to everybody who would listen that it was politics. She just had nothing at all good to say about the head coach, the program, etc. (To be fair, said coach, though extra-ordinarily successful, is both widely reviled and widely praised, so somewhat of a controversial figure. So lots of people say about him what the hot, hot-headed mom says. But lots defend him too. Plus I was in fact surprised that he was cut. He played well enough for our travel team that we were all surprised.)
Anyway, the kid kept trucking. Despite not playing at all junior year HS season, he kept playing for our travel team through summer and fall, he hit the weight room, worked really hard on his game with a personal instructor. He was determined to try out again as a senior (and encouraged to do so by our travel coach.) He had no expectations of making it (which isn't surprising given what he was hearing from his Mom.). He more wanted to try out to "show" the coach, I gather.
Well, you know what? Coach called him in his office, congratulated him on his off the chart work ethic, told him he had improved an incredible amount, and gave him a spot on the team.
That's "politics" for you, I guess.
