7. Tiger Woods, Hero World Challenge

This one drew serious attention because everything involving Woods draws serious attention. Slow-motion replays showed a potential double-hit on No. 18 in the second round of the Hero World Challenge, but a relatively new rule meant Woods didn’t receive a penalty. And we won’t be seeing any further issues on this one considering double hits are no longer a penalty under the modern rules of golf.
