Well first of all any drop that goes outside two club lengths must be dropped. Any ball that goes nearer the hole must be replaced , what if the "rub of the green" has the ball rolling closer to the hole.
The ball must be putted from where the ball came to rest on the green unless relief is needed to be taken.
It's not a drop though.
Ok, although we have the answer already I'll throw this scenario which I'm sure you know the answer to anyway which kinda formed part of my earlier thinking.
1 - you are on the putting green and mark your ball, after replacing your ball the ball is then blown by the wind nearer (or further) from the whole, what do you do?
