I'm not sure how you assume that Clipper pick is in the 20's now. Nobody knows that. For me, it could go either way.
For the Eastern Conference sake, they better hope Ainge doesn't get a 11-15 pick in a deep draft.
The most important thing right now is for them to not win their divison. Their only competition there are the lakers and maybe golden state. In order for them to miss the playoffs we need the southwest to be really strong. The Mavs, Grizzlies, Spurs and Rockets are all in that division. At least three of them need to make the playoffs. Then you've got the nuggets, jazz and okc in the northwest.
Here's the list of contenders:
Clippers
Lakers
Warriors
Mavericks
Grizzlies
Spurs
Rockets
Jazz
Nuggets
Thunder
That's 10 teams. We need the clippers to be in the 9-10 range to be an 11-15 pick, pretty much.
Hopefully Golden State can come away with Chris Paul or something.
