Obviously totally hypothetical but....what if one of the sisters wasn't born? Let's say it was only Venus or Serena that Richard had to mold. Would either one of them have been the successes they are today if they hadn't had the other pushing them? It's easy to say now that if venus wasn't around, Serena would have more Slams and vice versa. But then again maybe not..like Chirs Evert talks about Martina pushing her to get better, if one sister didn't have the other maybe they wouldn't have become one of the all-time greats. Thoughts?

Just off the top of my head, their overbearing & obnoxious father would probably still be enough to push just one of them into success.
