The account of Yellow is true. He did just enough to win. If you win in 30 minutes, most of the time you're beating just a dog that really has no business being in the box to begin with. Any dog that wins a legitimate 6 matches is something special. When you consider most dogs don't win 1 match, let alone 6, it puts things in a certain perspective. His sire, Yellow John, was the same way. So you at least know he got it honest.
