(lie locations are approximate, of course)
A couple of important notes:
- He took a meter off the OB line before taking relief. As others have said, this is legal.
- Smith only took relief backwards by 5 or 8 feet.
- Hebenheimer specifically said "You don't get a meter the second time, though", which is correct.
- Hebenheimer walked behind him, checked out the line, checked out his new lie, and declared it legal.
All of those combine for me to say it looks legal to me. If he had gone farther backwards, like 20' or more, he would have run into the OB line again. However, only moving back 5' or 8' didn't really bring the OB fence back into play.
Judging solely from video, I would have said it looked "close enough to legal" to not complain about. Once Hebenheimer jumped in with his accurate knowledge of the rules and his line-check, I'm confident that it was legal.
So basically, it seems there is a consensus that the title of this thread is the thing that is incorrect.
