SCOTTSDALE, Ariz. – In golf, as in life, cheating and breaking the rules are two very different actions with very similar consequences. Kick your ball from the rough into the fairway and you’re subject to penalty. Ground your putter only to see your ball oscillate slightly and you’re also subject to penalty, even if the intent wasn’t the same. In the aftermath of revelations that Vijay Singh has used deer-antler spray that contains IGF-1, a chemical banned under the PGA Tour’s Anti-Doping Policy, observers will be trying to differentiate between whether he cheated or simply broke a rule. It’s a major distinction as far as the Hall of Fame member’s public image, but mere semantics when it comes to the letter of the law.
