Well the ping pong balls belonged to the Nets so any previous bad luck with Celtics ping pong balls has no effect on this outcome 
you have a good point . in terms of good faith trade , there should be no bad karma associated with the trade. Great players were given up for the chance to sign a great young talent to replace them . Fair winds blew our way and we have a top four . No reason the luck could not give us 1-3 either.
i think our most lkely outcome will be pickng second ......then taking Jackson
Suns pick first ....take Fultz or Ball
Lakers pick third take Ball
1 Suns , 2 Boston , 3 LA. ....seem to come up most often , then Boston picking Forth seemed to come up,alot .....ugh. .....because we got 75 chance of NOT getting 1st.
my prediction is we end up with Jackson with 2 or 3 pick
