Milwaukee clinched the conference's top playoff position with a 130-116 win over the Miami Heat on Thursday.
Since the Los Angeles Lakers already locked up the Western Conference, the top seeds are off the table.
Miami also won its season series with Philadelphia and would capture its series against Indiana by winning one of the two games these teams will play inside the bubble.
The Sixers might be sixth in the current standings, but FiveThirtyEight gives them a 10 percent chance of winning the title (tied for fourth-highest overall).
Houston, paced by former MVPs James Harden and Russell Westbrook, is the team tied with Philadelphia for having a 10 percent chance of winning the title, per FiveThirtyEight.
