Those Sixers fans masquerading as Celtics fans won't want Philly to win this one , get too close to the Lakers and screw up their 25% shot at Simmons. 
Good (tommy) point
Technically if the season ended today, Philly would have a 33.8% chance at Simmons seeing as they can swap picks with the Kings and the Kings have the 5th worst record.
But I'm not sure how Philly winning this would have anything to do with the Lakers. Lakers aren't finishing with a worst record than Philly. Lakers need to lose all the games they can, because if they fall out of the top 3 (45% chance of happening right now), their pick goes to Philly... but it would be pretty surprising if the Lakers finished with a worst record than Philly this year.
What you're really trying to say is...
As a Celtic fan, we want Brooklyn to lose so the pick they owe us stays juicy.
As a Laker hater, we want Philly to lose so it hurts the Lakers chance of having the top draft odds.
I don't think it would be at all surprising if Philly ended up with a similar record to LA at the end of the year. On one hand people say Wroten, Thompson, Okafor, Noel, Stauskas, Thompson are all NBA caliber players, but the on the other hand they will win 4 games all year. It can't be both.
I know that what's I don't get. Okafor and Noel are supposedly future superstars, but the team is worse than last year. Were the early Durant/Westbrook teams this bad?
Noel is, right now, a tremendously limited player. Okafor was a bad defender in college. The next best guy on the roster is probably no better than the 9th guy in a good team's rotation. The rest of the team would be lucky to get 10 day contracts.
So, Noel and Okafor aren't that good but they're surrounded by much worse talent.
