Not really sure where the bad blood thing comes from. I had never heard of it before this.
Dennis was not exactly Mr. Happy at the World 9-ball Championships when SVB drilled him.
It was also SVB that called the foul on when Dennis attempted to use a object ball to make a measurement and that was not a pleasant little conversation at the time.
Dennis is a pretty serious competitor and he does not like to lose. Lately every time he has played SVB all he does is lose over and over and it seems to be getting to Dennis a bit.
It is one thing to have a fierce rivalry between two champions that goes back and forth, it is another thing when one champion starts to make the other guy into his personal punching bag. Dennis has been getting beat on pretty consistently by SVB and has not managed to do much damage back.
