All this confusion about who should win this year's Most Valuable Player stems from the fact that the role of an MVP is not clearly defined. Because there is no set criteria the voters can follow, there is a lot of debate.
To understand what the voters might be thinking, I am presenting three different schools of thought determining what characterizes a most valuable player.
Definition One: Best Player on the Best Team—Kevin Garnett
In the Dirk Nowitzki model, Garnett would win the award because he is the best player on and leader off the best team in the NBA, the Boston Celtics. He has revived the Celtics, but because he has not had a career year, he probably won't win the MVP award.
Definition Two: Most Indispensable Player—LeBron James
Without LeBron, the Cavaliers would be the worst team in the NBA, just like they were before they got him. LeBron carries the Cavaliers every night, even when teams are focused solely on defending him.
Definition Three: Most Outstanding Player—Kobe Bryant
I concede that Kobe is the best player in the league. He is the complete package. His offense, defense, and teamwork set him apart.
