This has some extremely dubious arguments in it. Saying he missed 2 out of 3 free throws at the end of the game to make a point about clutchness when one of them was missed on purpose to give the Cavaliers a chance to win when down 2 with 1 second left is very disingenuous. Not to mention, if you look at the Cavaliers average point differential they grade out as a 44 win team instead of a 50 win team, meaning they won more close games than expected, which is a good indicator Lebron played well in the clutch.
As for some other points you made, the Cavs record would have put them in 3rd in the West, the West only won about 2% more games than the East overall, and it's not like Harden was some amazing teammate for Dwight Howard last year. None of this is to say that Harden isn't deserving of MVP, but Lebron not getting the award isn't because of any of the reasons you stated.
Thank you for your comments...the fact that the Cavs play in the East makes their overall strength of schedule WAY less than any team in the West.
