Well the MVP award is for the current year, so that bodes well for Westbrook. If it were for multiple years, you would have a point. Lebron's impact on the league is irrelevant to the award by definition and he plays on the team with the highest payroll in history, so let's not pretend we are talking about Cavaliers circa 2007, James Harden did as much to get his team where they are. Lebron also had quite a few "DNP - rest" games. Hard to give the regular season MVP to a guy who basically acted like the regular season was irrelevant; a foregone conclusion.
Also, they lost tonight. SAD!
