I didn't read every post but I will say for the Celtics sake if this rule is implemented I hope it's not until after 2018. The reason I say that is because for a year or 2 it will make the draft really weak, as all the kids that would have been one and done are forced to stay, and the draft will be made up of older kids that weren't talented enough to go out earlier.
With all our potential high picks coming our way I would hate to miss out on someone if this rule just went into place.
