Let's revive an old Grantland tradition and ask who's on notice after the whirlwind of the last 48 hours.
The top of the East
Assuming Philadelphia, Milwaukee, Boston, and Toronto all advance, I'm not sure there will have ever been a playoff round with more potential to swing superstar free agency than the conference semifinals in the East. Two of these four must lose. Lose badly, and eyes will wander.
• Even the placid Bucks have the four starters entering free agency. Keeping all of them might vault Milwaukee into the luxury tax. Are they willing to do that if they lose in the second round?
