SECAUCUS, N.J. -- At the 1987 NBA Draft Lottery, David Stern pulled seven envelopes out of a barrel. The San Antonio Spurs ended up with the No. 1 pick and David Robinson. The Phoenix Suns got the No. 2 pick and were stuck with Armon Gilliam.
In 1997, the Spurs leapfrogged the Boston Celtics in the draft lottery and walked away with Tim Duncan. The Celtics have yet to find a dominant center or a place in the NBA Finals.
In 2002, the Houston Rockets struck lottery gold again, leapfrogging five teams to draft five-time NBA All-Star Yao Ming. The two teams with the worst records, the Bulls and Warriors, ended up with Jay Williams and Mike Dunleavy.
Now in 2007, 14 teams find themselves waiting to find out whether they will get franchise center Greg Oden, dynamic forward Kevin Durant or, in some cases, knocked out of the lottery altogether.
As the lottery approaches on Tuesday (ESPN, 8:30 ET), let's look at which teams have the most at stake.
We're doing something different this year -- rating each team on a Disaster Meter, based on how catastrophic it would be for the team not to get one of the first two picks.
And we're ranking the teams from highest to lowest on the Disaster Meter.
A rating of 10 represents the apocalypse. A rating of 1 means everyone grins and bears it.
