The Roger Clemens trial just getting under way comes down to a tale of two men.
It's about a baseball star and his trainer who rose together to the heights of their professions only to become bitter enemies.They've ultimately destroyed each other's reputations as stand-up
family men who were the best at what they did.
The mutual damage is bound to get worse over the next few weeks as Clemens is tried on charges he lied to Congress when he denied ever using performance-enhancing drugs.
Clemens' former trainer, Brian McNamee, says he injected his star client repeatedly with steroids and human growth hormone and even saved some of the needles and gauze.
Clemens says McNamee is a liar who fabricated the evidence with designs on blackmailing him.
