I've done some calculations, and this is how it stands.
EAST
If the Celtics maintain the same win percentage, the Magic need to go 21-7 to have a chance at the playoffs.
The Bulls need to go 20-9, and Washington has realistic hopes, they need to go 19-13.
Atlanta still could annoy, they have to go 17-12 to have a chance.
The Cavs need to go 15-14 to be in the same win range as the Celts currently are. If they can go 17-12 they'll have a real good chance.
This is all relative, if the 8th place team in the EAST wins 35 games, and basically everyone stays about steady.
WEST
Phoenix is out if Denver stays steady, to get the same win percentage as Denver, they need to win 47 games total, which would mean 29 more games, but they only have 27 games left.
So basically Phoenix is done.
The Clippers still have a long shot chance, but we all know its not happening, but if they go 25-6 in the rest of their games, they have a chance at the playoffs.
The Warriors need to go 24-7 to have a chance, which is also pretty hard to attain.
Portland needs to go 23-8, Seattle 22-8, and Utah has to go 21-8.
All these are baring that Denver maintains their win percentage, which means them going 16-12. Basically, the 8th place team in the West needs to win 47 games total.
