The story of the NBA playoffs first round is most commonly breakout performances by the could-be future of the league, and the 2017 first round has certainly not lacked such standouts. John Wall has led the Wizards, the Greek Freak has led the Bucks, and we haven't even discussed the two-man MVP race going head to head out West in Russell Westbrook and James Harden. Who has been the most impressive thus far in the first round? There has also been a very surprising development out in the East as the first seed Celtic find themselves trailing to the largely disappointing Chicago Bulls. Can the Bulls complete the upset, and what does that mean for the East as a whole?
