Well...she's six. Not every six year old needs or wants a lot of (or even one) structured activities. School is enough. Extras are great if a kid wants to try them, but what is the point if everyone is miserable? If she is active otherwise, she has PLENTY of time to decide if she's interested in team sports.
Thing is, when my 6-year old is at home, she inevitably says, "mommy, I'm boooooored.' She has toys, crafts, games, all of which I am willing to do with her, and all she wants to do is..... you guessed it, watch TV. She would watch TV all day if she was allowed.
So I think just saying ok, no activities, is too simplistic an answer.
