I personally think that the MVP award should go to Kawhi Leonard mainly because hes is an ideal two way unstoppable force and is the best player on the 2nd best team in the League.
Curry and Lebron James who are probably the best two players in the league, wont rack up many votes despite being on the best teams in their conferences,mainly due to sharing the ball with superstars and very high expectations from their previous seasons which make their current seasons which are definitely MVP worthy ones,a step down from their peak years.
However, i think Jmaes Harden who is having an amazing offensive season will probably get the nudge over Russ because of his team's better position as the history of the award suggests.
Needless to say i think its probably the most wide open race for the MVP, with Gordon Hayward,John Wall and Isaiah Thomas putting up career years to lead their team to a very respectable position in the standings.
