BOSTON -- A couple years ago the Boston Celtics hit the lottery night jackpot in landing the top overall pick.
They sent it to Philadelphia and wound up getting Jayson Tatum two spots later, and a future first-round pick that they hope to cash in tonight for another potential lottery pick selection.
The Celtics have no shot at getting the top overall selection during tonight’s lottery draft selection, but there is a slim shot that they may wind up with a pair of lottery picks depending on how good a bounce they get from picks that belong to Sacramento and Memphis, both of whom could potentially convey their first-round picks this year to Boston.
Here’s a look at other highlights of tonight’s ping-pong ball process that could potentially alter the trajectory of many franchises, Boston included.
Time: 8:30 p.m. ET
Where: The Hilton Chicago
Best odds for No. 1
New York, Cleveland and Phoenix each have a 14 percent chance of landing the No. 1 pick, followed by Chicago (12.5 percent) and Atlanta (10.5 percent).
Best-case scenario for Boston
* Sacramento moves up to No. 2; that pick is then conveyed to Boston
* Memphis pick stays within the top-8. That means Boston won't get the pick this year. It will instead be conveyed next year when it is only top-6 protected or in 2021 when it is unprotected.
Celtics' odds for each pick
#2 pick — 1.1%

How the lottery works, explained by NBA.com
Drawings will be conducted to determine the first four picks in the NBA Draft. The remainder of the “lottery teams” will select in positions five through 14 in inverse order of their 2018-19 regular-season records. The actual lottery procedure will take place in a separate room just before the national broadcast. Select media members, NBA officials and representatives of the participating teams and the accounting firm of Ernst & Young will be in attendance for the drawings.
Fourteen ping-pong balls numbered 1 through 14 will be placed in a lottery machine. There are 1,001 possible combinations when four balls are drawn out of 14, without regard to their order of selection. Before the lottery, 1,000 of those 1,001 combinations will be assigned to the 14 participating lottery teams.
The drawing process occurs in the following manner: All 14 balls are placed in the lottery machine and they are mixed for 20 seconds, and then the first ball is removed. The remaining balls are mixed in the lottery machine for another 10 seconds, and then the second ball is drawn. There is a 10-second mix, and then the third ball is drawn. There is a 10-second mix, and then the fourth ball is drawn. The team that has been assigned that combination will receive the No. 1 pick. The same process is repeated with the same ping-pong balls and lottery machine for the second through fourth picks.
If the same team comes up more than once, the result is discarded and another four-ball combination is selected. Also, if the one unassigned combination is drawn, the result is discarded and the balls are drawn again. The length of time the balls are mixed is monitored by a timekeeper who faces away from the machine and signals the machine operator after the appropriate amount of time has elapsed.
Darrington Hobson, a partner in the accounting firm of Ernst & Young, oversees the entire lottery process and stuffs and seals the envelopes before bringing them to the studio for the broadcast. The announcement of the lottery results will be made by NBA Deputy Commissioner Mark Tatum. A second representative from each participating team will be seated on stage. Neither the Deputy Commissioner nor the team representatives on stage will be informed of the lottery results before the envelopes are opened.
The team whose logo is in the last envelope opened will have the No. 1 pick in the 2019 NBA Draft, to be held on Thursday, June 20 at Barclays Center in Brooklyn, N.Y.
