In the NBA playoffs, every possession is important. Each shot matters, all the defensive stops count and every single player makes a difference.
Nonetheless, one player still manages to stand out on each of the 16 playoff squads as the single most important guy. He's the one most crucial to the team's success.
The most important player isn't necessarily the best player. He's not always the X-factor, although in some cases, he very well could be. An X-factor is usually more of a wild card, a player capable of exploding and swinging the balance of either a game or a series.
These players are expected to perform at a high level, but it would be absolutely devastating if they didn't.
If you're a fan lucky enough to be rooting for one of the 16 teams competing in the NBA postseason, you better hope that your most important player lives up to the expectations and does his job.
