I had a "Bo" when I coached Babe Ruth baseball (when it was what kids played). The kid (14) was already a man physically at 6'2". I didn't know his weight. But he was built like a rock. He was fast as hell. He beat me in a foot race when I was one year removed from college ball running a 6.6.
This kid was destined to star in baseball and football in high school. His attitude got in the way. He told everyone he was the best. He acted entitled. He mentally tortured the younger players.
I warned him. One time I thought we were going to have a physical confrontation. Then I warned him he was in danger of being kicked off the team. Then to the shock of the team I kicked him off the team. Everyone relaxed, played well and we won the league championship.
The kid never played varsity baseball or football. He was kicked out of both high school programs. He did get a full ride though. He played football and baseball for State Penn.
There's a lot more to the story. He's the one kid I couldn't reach no matter what I tried. He's spent his life in and out of prison.
