Never could've happened. Kobe wanted to go to LA or New York and wouldn't report for any other team that drafted.
That said:
What if the Hornets traded Kobe to New York instead of LA?
Other ones:
What if the Pistons treated Grant Hill's injury correctly and he stayed in Detroit?
What if Lakers traded Kobe instead of Shaq?
What if the Bulls never traded Oakley for Wellington (thus never giving them a real center)?
What if the Bulls didn't trade Brand to the Clippers?
What if the Malice In The Palace never happened?
What if Jordan was a member of the (enter team here)'s Front Office in 2001 instead of the Wizards?
What if the Pistons didn't trade Stackhouse for Rip?
What if Isiah Thomas wasn't offered a job with the Knicks?
What if the Grizzlies got the First draft pick in the LeBron draft, instead of Number 2, Making the Draft Order Grizz/Cavs/Nuggets/Raptors/Heat?
What if Bird didn't wait a year after being drafted to play in the NBA?
What if Kareem didn't get injured in the Finals, forcing Magic to start at Center and essentially speed up his career?
What if Vince Carter made the last second shot in the 2001 Eastern Semis, making the ECF Bucks/Raptors instead of Bucks/Sixers? (my personal favourite)
What if the Nets didn't have to pay the Knicks for territorial rights to join the NBA, saving them from having to trade Dr. J to the 76ers?
What if there wasn't a Lock out in 1998-99 and the Bulls were able to bring back Jackson/Jordan/Scottie (but not Rodman, since he was being pushed out of Chicago by that point by the other three)?
What if Jordan didn't return and Kwame was allowed to develop without Jordan's on court pressure?
