My 17 year old son got into some trouble at his private school and was politely asked to leave last week. He played #3 singles for his varsity team at the 4A level (it's a 2A school that plays up) and was undefeated this year in the first three matches. When we registered him at his new school we found out he couldn't play varsity (he's a senior) because of an anti-recruiting rule. They said he could play JV but he's not interested. This pretty much kills any chance of him getting on a college team, and has turned him off of tennis. I think it's a stupid rule, but I may be biased.
First, I know it must be disappointing to your son to be at a new school, new kids and now to be off the tennis team.
But, as the parent you need to put it all in perspective.
I think the tennis team at his new school is the least of your/his problems.
The first question is how has his chances for college been affected by his poor decision making?
A change in senior year will have to be explained.
And if he can't make the tennis team,
how about he uses that after school time to volunteer and teach tennis to some disadvantaged kids.
One his time will be used wisely ( stays out of trouble ) and two, it will help play down the "trouble".
The perspective is that he didn't get into a car and kill someone. He is not in jail.
The key is to nip his troublesome behavior before it lands him into real problems.
