NBA: 5 big questions heading into the All-Star break

Which East team will emerge as the biggest threat to the Brooklyn Nets?

Even though the Brooklyn Nets are technically not sitting atop the Eastern Conference at the moment, most, if not all, consider this team as the favorite to make the NBA Finals in the East. However, which team will emerge as the biggest threat to possibly take them down?

Will it be the Philadelphia 76ers, who have sat atop the East for what feels like all season long? Will it be the Milwaukee Bucks, who have flown under the radar thus far in the first half of the season? Or perhaps the Boston Celtics will right the ship during the second half of the season to join the conversation?

Then again, maybe the Nets are simply too talented for any other team in the Eastern Conference to test them in the playoffs? Either way, it should provide theater to the second half of the season, and into the playoffs, in the East.
