I'm with John here. I watched several games and saw no evidence of a dump or "business." It is entirely possible that they are making a "saver" here, but that is something entirely different than a dump. When there are thousands on the line many pros will "save" something, like $500 or a $1,000. That is a normal and acceptable practice. They are still playing to win though!
Rodney's playing style is fast and loose, so it may look like he is taking the match too lightly sometimes. Not so, that's his way of staying relaxed and avoiding the pressure. I saw two players playing their best pool and both trying to win. That's my opinion. I think to say otherwise does a disservice to both men.
Jay, I think you nailed this one.
If anyone has watched Rodney more than once, they would know that his fast and loose style turns around and bites him once in a while.
Also, IIRC, Rodney's break just wasn't working when he was playing Raj. That is a huge difference in a match like this.
