Answer

You could say: "When I was a child, I used to play for a basketball team."
or 
"When I was a child, I used to play on a basketball team." 
But you could not say "When I was a child, I used to play in a basketball team." That is incorrect.

Answer

It is perfectly OK to say; "When I was a child, I used to play in a basketball team."

When I was a kid, I used to play in a soccer team every winter.
